Dr. %maroon%'''WangQ Lim'''%% (Uni. Osnabrück) will give a talk in the AAG Oberseminar on May 3 on %green%''Edge Analysis and identification using the Continuous Shearlet Transform''%%.
%abbox% %maroon%Abstract%%: It is well known that the continuous wavelet transform has the ability to
identify the set of singularities of a function. It was recently shown
that certain multidimensional generizations of the wavelet transform are
useful to capture additional information about the geometry of the
singularities.\\
In this talk, we show that the continuous shearlet transform allows
one to exactly identify the location and orientation of the edges of
planar objects. This provides the theoretical background for the
development of improved algorithms for edge detection and analysis.\\
If time is allowed, we also discuss some recent results (by Guo and
Labate) on edge analysis using 3D shearlets.\\

%abbox% %maroon%Abstract%%: Recently introduced multiscale directional representations such as the curvelet and shearlet systems have been shown to be particularly effective at characterizing edge discontinuities of planar regions. In this talk, we show that this approach can be generalized and extended to deal with general singularities not only in the plane but also in higher dimensions. This investigation is motivated by applications in edge detection and feature extraction for 2D and 3D data.

%abbox% %maroon%Abstract%%: Solutions of certain PDEs and variational problems may be characterized by "a few significant degrees of freedom", and one may want to take advantage of this feature in order to design efficient numerical solutions. Examples of such situations are ubiquitous: adaptive solution of PDEs, degenerate PDEs for image processing, crack modelling and freediscontinuity problems, viscosity solutions of HamiltonJacobi equations, digital signal coding/decoding, and compressed sensing. In this talk we focus on methods for the compressed solution of PDEs and we address three different topics.\\
1) Adaptive numerical methods for elliptic PDEs by means of redundant frame discretizations;\\
2) Numerical methods for 1Laplacian equations associated to total variation minimization;\\
3) Inverse freediscontinuity problems. \\

%abbox% %maroon%Abstract%%: Operator splitting techniques were developed in the 60th for the efficient solution of linear systems of equations appearing in connection with the numerical solution of partial differential equations. More than 20 years later these methods were generalized to nonlinear, setvalued, monotone operators and were recently successfully applied in image precessing. After motivating why methods of convex analysis/nonsmooth convex optimization are useful for many image restoration tasks we give a brief introduction into the relevant operator splitting techniques. We point out that for special functionals there exist equivalent derivations via averaged operatoren, (Bregman) proximal point methods or augmented Lagrangian methods. Then we present applications of operator splitting methods in directionsteered inpainting (interpolation) and for denoising of images corruped with nonadditive noise (and possibly some blur) which appear for example in Synthetic Aperture Radar and electronic microscopy.

%abbox% %maroon%Abstract%%: Fourier series provide a way of writing almost any signal as a superposition of pure tones, or musical notes. But this representation is not local, and does not reflect the way that music is actually generated by instruments playing individual notes at different times. We will discuss timefrequency representations, which are a type of local Fourier representation of signals. This gives us a mathematical model for representing music. While the model is crude for music, it is in fact a powerful mathematical representation that has appeared widely throughout mathematics (e.g., partial differential equations), physics (e.g., quantum mechanics), and engineering (e.g., timevarying filtering). We ask one very basic question: are the notes in this representation linearly independent? This seemingly trivial question leads to surprising mathematical difficulties.

%maroon%'''Andreas Heinecke'''%% (Uni. Missouri) will give a talk in the AAG Oberseminar on April 26 on %green%''Constructing Fusion Frames''%%.
%abbox% %maroon%Abstract%%: Following their introduction by Casazza and Kutyniok, tight fusion frames have been shown to be robust against additive noise and erasures and thus are well suited for applications in communications or compressed sensing. An important method for deriving fusion frames is the spectral tetris construction recently introduced by Casazza, Fickus, Mixon, Wang and Zhou. In this talk we will show how this tool can be used to construct fusion frames with desired properties, such as predetermined ranks of the projection operators or predetermined eigenvalues of the fusion frame operator.\\

%abbox% %maroon%Abstract%%: The Pythagorean Theorem should be known to everyone after completing elementary school. However, its generalization for orthogonal projections might not be widely known among professional mathematicians due to the fact that it was proved only a few years ago. This theorem characterizes diagonals of orthogonal projections in Hilbert spaces and it was shown in 2002 by Kadison. For finitely dimensional spaces this result is a consequence of a more general SchurHorn Theorem characterizing diagonals of Hermitian matrices with prescribed eigenvalues. In the finite dimensional case diagonals of a projection are numbers between 0 and 1 summing up to an integer. However, the infinite dimensional case, though simple in formulation, is a much deeper result.

%abbox% %maroon%Abstract%%: Dahlke, Steidl and Teschke recently introduced a continuous shearlet
transform for higher dimensions. In this talk we focus on such
(discrete) shearlet systems in 3D with compact support. We derive
sufficient conditions for socalled coneadapted shearlet systems to
form a frame and provide explicit estimates for their frame bounds. If
time permits, we also discuss their sparse approximation properties
for representing functions which are {$C^2$}smooth except on a {$C^2$}

%abbox% %maroon%Abstract%%: A 50 year old problem in Engineering asks: Can we do signal reconstruction
without phase? This problem is fundamental to a number of questions in Engineering and Applied Mathematics including the famous "Cocktail Party Problem". We will look at the recent solution to this problem which relies on techniques from Hilbert space frame theory. The emphasis will be on the mathematics underlying the problem and the solution to the corresponding mathematical questions. No previous knowledge is required as all needed ideas will be developed in the talk.\\

%abbox% %maroon%Abstract%%: In this talk will discuss two recent topics in sparse recovery. Many types of realworld signals (e.g. sounds, images, video) can be viewed as an {$n$}dimensional vector of real numbers, where usually {$n$} is really large, that is "compressible". Sparsity is a simple but effective model for many reallife signals. Compressed sensing (CS) concerns linear algebra and underdetermined linear equations with a sparsity constraint. First we will discuss compressed sensing and its applications in different area of mathematics, especially the possible connection to PDEs using finite elements. In the second part of this talk, we will consider the Kronecker product of matrices. We discuss different sparsity measures such as restricted isometry property (RIP), null space property (NSP), mutual incoherence, spark and their connections and how these measures behave in the case where the matrix is the Kronecker product of matrices.

Prof. %maroon%'''Gitta Kutyniok'''%% gave a talk in the AAG Oberseminar on January 21 on %green%''Frames, Fusion Frames, and Sparse Recovery''%%.
%abbox% %maroon%Abstract%%:
This talk will discuss two recent results in frame and fusion frame theory:\\
''Frames'' have been a focus of study in the last two decades in applications where
redundancy plays a vital and useful role. However, although the notion of redundancy
is at the heart of frame theory, in the case of finite frames, no quantitative notion
has been established yet.\\
In the first part of this talk, we introduce and discuss a list of desiderata a
rationally defined quantitative notion of redundancy for a finite frame shall satisfy.
We then propose a notion of upper and lower redundancy which, in particular, satisfies
all properties advocated in the desiderata. This is joint work with Bernhard Bodmann and
Peter Casazza.\\
As technology progresses, signals and computational sensing equipment becomes
increasingly multidimensional. Sensors are being replaced by sensor arrays and
samples are being replaced by multidimensional measurements. Yet, modern signal
acquisition theory has not fully embraced the new computational sensing paradigm.
''Fusion frames'' are recently emerged mathematical structures that can better capture
the richness of natural and manmade signals compared to classically used
representations.\\
In the second part of this talk, we will introduce the notion of fusion frames
and discuss several results on sparse recovery using fusion frame expansions in both
a worstcase and an averagecase analysis framework. This is joint work with Petros
Boufounos and Holger Rauhut.\\

%abbox% %maroon%Abstract%%: Geometric knot theory is the study of geometric properties of space curves that derive from their topological knottedness. Perhaps the most famous result is the Fary/Milnor theorem relating total curvature to bridge number, but the field can be dated back to work of Pannwitz on quadrisecant lines for knots. There has been a surge of interest in geometric knot theory over the past 15 years, partly due to biophysical applications to the shapes of knotted polymers like DNA molecules. One interesting problem with some surprising answers asks for the shapes of knots and links tied tight in rope of fixed thickness. We will survey recent results on this socalled ropelength problem, as well as some new strengthened versions of the theorems of Pannwitz and Fary/Milnor. We will also give a partial answer to a question of Gromov on distortion of knots. (''Kolloquium, Wed. 16.12.2009 at 17:00, Uni. Osnabrück, Building 69/125'')%%
Dr. %maroon%'''Felix Krahmer'''%% (University of Bonn) gave a talk in the AAG Oberseminar on Dec. 10 2009 on %green%''Lower Bounds for the Error Decay in OneBit Quantization''%%
%abbox% %maroon%Abstract%%:
Several analogtodigital conversion methods for bandlimited signals used in applications,
such as {$\Sigma\Delta$} quantization schemes, employ coarse quantization coupled with oversampling.
The standard mathematical model for the error analysis of such methods measures the
performance of a given scheme by the rate at which the associated reconstruction error
decays as a function of the oversampling ratio {$\lambda$}. It was recently shown that exponential
accuracy of the form {$O(2^{r\lambda})$} can be achieved by appropriate onebit SigmaDelta modulation
schemes. However, the best known achievable rate constants {$r$} differ significantly from the
general information theoretic lower bounds. In particular, no lower bounds specific to onebit
quantization schemes were known. In this talk we show the first such lower bound for the
error decay rate. Our method is based on large deviation estimates. This is joint work with
Rachel Ward.

%abbox% %maroon%Abstract%%: Subdision schemes generate curves or surfaces from discrete data by means of repeated local and stationary refinement of that data, based on very simple rules. The initial data can be scalar or vector valued and the vector components can represent multiple data or derivative information. Any investigation of approximation order or smoothness (in the sense of derivatives) of the resulting limit functions naturally leads to factorization properties of certain Laurent polynomials. While in one variable things are still quite simple and all reduces to a linear factor of the form 1+z, the multivariate situation becomes more exciting as now quotient ideals in the ring of Laurent polynomials are involved, a ring that is fundamentally different from the ring of polynomials. In this talk I want to introduce some of these less freightening than natural connections and point out some consequences of this nice connection between analysis and algebra.

%abbox% %maroon%Abstract%%: In this talk I will discuss some aspects in the interplay of mathematics and medicine with particular focus on two examples from cardiology: (i) The quantitative diagnosis of perfusion with PET techniques, (ii) the characterization and therapy of cardiac arrythmias using ECGI techniques. I shall discuss some mathematical questions arising from those imaging and inversion tasks, related to modelling, analysis, and numerical simulation. Moreover, I will highlight the interactive nature between the formulation of diagnostic targets and (to a lower extent) therapeutic strategies, and the formulation and solution of mathematical problems.

Dr. %maroon%'''Philipp Grohs'''%% (Vienna and Graz University of Technology) gave a talk on Oct. 19 2009 on %green%''Some new results in Shearlet theory''%%
%abbox% %maroon%Abstract%%: The first part of the talk focuses on the question of which conditions
a function {$\psi$} needs to satisfy in order to qualify as a shearlet.
By this we mean that it must be possible to represent any
{$L^2$}function {$f$} by sheared and scaled translates of {$\psi$} and that
the decay rate of the shearlet coefficients gives precise information
about the microlocal behavior of {$f$}. We show that essentially all
that is needed for {$\psi$} to fulfill these requirements are sufficiently many
anisotropic vanishing moments.
In the second part we adress the problem of combining the shearlet
concept with the concept of Multiresolution Analysis. Our approach is
to construct 'shearlet scaling functions' which satisy a refinement
relation adapted to the shearlet structure. This construction utilizes
a novel kind of subdivision procedure. (''Oberseminar, Mon. 19.10.2009 at 16:15, Uni. Osnabrück, Building 69/E15'') %%

%abbox% %maroon%Abstract%%: Following their introduction by Casazza and Kutyniok, tight fusion frames have been shown to be robust against additive noise and erasures and thus are well suited for applications in communications or compressed sensing.

In this talk we will show how this tool can be used to construct fusion frames with desired properties, such as predetermined ranks of the projection operators or predetermined eigenvalues of the fusion frame operator.\\

%abbox% %maroon%Abstract%%: The Pythagorean Theorem should be known to everyone after completing elementary school. However, its generalization for orthogonal projections might not be widely known among professional mathematicians due to the fact that it was proved only a few years ago. This theorem characterizes diagonals of orthogonal projections in Hilbert spaces and it was shown in 2002 by Kadison. For finitely dimensional spaces this result is a consequence of a more general SchurHorn Theorem characterizing diagonals of Hermitian matrices with prescribed eigenvalues. In the finite dimensional case diagonals of a projection are numbers between 0 and 1 summing up to an integer. However, the infinite dimensional case, though simple in formulation, is a much deeper result. In this talk we shall describe Kadison's theorem and some newer results characterizing diagonals of selfadjoint operators with prescribed spectrum.

Many types of realworld signals (e.g. sounds, images, video) can be viewed as an {$n$}dimensional vector of real numbers, where usually {$n$} is really large, that is "compressible". Sparsity is a simple but effective model for many reallife signals. Compressed sensing (CS) concerns linear algebra and underdetermined linear equations with a sparsity constraint. First we will discuss compressed sensing and its applications in different area of mathematics, especially the possible connection to PDEs using finite elements. In the second part of this talk, we will consider the Kronecker product of matrices. We discuss different sparsity measures such as restricted isometry property (RIP), null space property (NSP), mutual incoherence, spark and their connections and how these measures behave in the case where the matrix is the Kronecker product of matrices.

''Frames'' have been a focus of study in the last two decades in applications where
redundancy plays a vital and useful role. However, although the notion of redundancy
is at the heart of frame theory, in the case of finite frames, no quantitative notion

%abbox% %maroon%Abstract%%: Fourier series provide a way of writing almost any signal as a superposition of pure tones, or musical notes. But this representation is not local, and does not reflect the way that music is actually generated by instruments playing individual notes at different times. We will discuss timefrequency representations, which are a type of local Fourier representation of signals. This gives us a mathematical model for representing music. While the model is crude for music, it is in fact a powerful mathematical representation that has appeared widely throughout mathematics (e.g., partial differential equations), physics (e.g., quantum mechanics), and engineering (e.g., timevarying filtering). We ask one very basic question: are the notes in this representation linearly independent? This seemingly trivial question leads to surprising mathematical difficulties.

%abbox% %maroon%Abstract%%: Geometric knot theory is the study of geometric properties of space curves that derive from their topological knottedness. Perhaps the most famous result is the Fary/Milnor theorem relating total curvature to bridge number, but the field can be dated back to work of Pannwitz on quadrisecant lines for knots. There has been a surge of interest in geometric knot theory over the past 15 years, partly due to biophysical applications to the shapes of knotted polymers like DNA molecules. One interesting problem with some surprising answers asks for the shapes of knots and links tied tight in rope of fixed thickness. We will survey recent results on this socalled ropelength problem, as well as some new strengthened versions of the theorems of Pannwitz and Fary/Milnor. We will also give a partial answer to a question of Gromov on distortion of knots. (''Kolloquium, Wed. 16.12.2009 at 17:00, Uni. Osnabrück, Building 69/125'')%%
Dr. %maroon%'''Felix Krahmer'''%% (University of Bonn) gave a talk in the AAG Oberseminar on Dec. 10 2009 on %green%''Lower Bounds for the Error Decay in OneBit Quantization''%%
%abbox% %maroon%Abstract%%:
Several analogtodigital conversion methods for bandlimited signals used in applications,
such as {$\Sigma\Delta$} quantization schemes, employ coarse quantization coupled with oversampling.
The standard mathematical model for the error analysis of such methods measures the
performance of a given scheme by the rate at which the associated reconstruction error
decays as a function of the oversampling ratio {$\lambda$}. It was recently shown that exponential
accuracy of the form {$O(2^{r\lambda})$} can be achieved by appropriate onebit SigmaDelta modulation
schemes. However, the best known achievable rate constants {$r$} differ significantly from the
general information theoretic lower bounds. In particular, no lower bounds specific to onebit
quantization schemes were known. In this talk we show the first such lower bound for the
error decay rate. Our method is based on large deviation estimates. This is joint work with
Rachel Ward.

%abbox% %maroon%Abstract%%: Subdision schemes generate curves or surfaces from discrete data by means of repeated local and stationary refinement of that data, based on very simple rules. The initial data can be scalar or vector valued and the vector components can represent multiple data or derivative information. Any investigation of approximation order or smoothness (in the sense of derivatives) of the resulting limit functions naturally leads to factorization properties of certain Laurent polynomials. While in one variable things are still quite simple and all reduces to a linear factor of the form 1+z, the multivariate situation becomes more exciting as now quotient ideals in the ring of Laurent polynomials are involved, a ring that is fundamentally different from the ring of polynomials. In this talk I want to introduce some of these less freightening than natural connections and point out some consequences of this nice connection between analysis and algebra.

%abbox% %maroon%Abstract%%: In this talk I will discuss some aspects in the interplay of mathematics and medicine with particular focus on two examples from cardiology: (i) The quantitative diagnosis of perfusion with PET techniques, (ii) the characterization and therapy of cardiac arrythmias using ECGI techniques. I shall discuss some mathematical questions arising from those imaging and inversion tasks, related to modelling, analysis, and numerical simulation. Moreover, I will highlight the interactive nature between the formulation of diagnostic targets and (to a lower extent) therapeutic strategies, and the formulation and solution of mathematical problems. This work is based on several collaborations with and data from the University Hospital Muenster and the European Institute for Molecular Imaging, Muenster.

Dr. %maroon%'''Philipp Grohs'''%% (Vienna and Graz University of Technology) gave a talk on Oct. 19 2009 on %green%''Some new results in Shearlet theory''%%
%abbox% %maroon%Abstract%%: The first part of the talk focuses on the question of which conditions
a function {$\psi$} needs to satisfy in order to qualify as a shearlet.
By this we mean that it must be possible to represent any
{$L^2$}function {$f$} by sheared and scaled translates of {$\psi$} and that
the decay rate of the shearlet coefficients gives precise information
about the microlocal behavior of {$f$}. We show that essentially all
that is needed for {$\psi$} to fulfill these requirements are sufficiently many
anisotropic vanishing moments.
In the second part we adress the problem of combining the shearlet
concept with the concept of Multiresolution Analysis. Our approach is
to construct 'shearlet scaling functions' which satisy a refinement
relation adapted to the shearlet structure. This construction utilizes
a novel kind of subdivision procedure. (''Oberseminar, Mon. 19.10.2009 at 16:15, Uni. Osnabrück, Building 69/E15'') %%

accuracy of the form {$O(2^{r\lambda})$} can be achieved by appropriate onebit SigmaDelta modulation
schemes. However, the best known achievable rate constants {$r$} differ significantly from the
general information theoretic lower bounds. In particular, no lower bounds specific to onebit
quantization schemes were known. In this talk we show the first such lower bound for the
error decay rate. Our method is based on large deviation estimates. This is joint work with
Rachel Ward.

%abbox% %maroon%Abstract%%: Subdision schemes generate curves or surfaces from discrete data by means of repeated local and stationary refinement of that data, based on very simple rules. The initial data can be scalar or vector valued and the vector components can represent multiple data or derivative information. Any investigation of approximation order or smoothness (in the sense of derivatives) of the resulting limit functions naturally leads to factorization properties of certain Laurent polynomials. While in one variable things are still quite simple and all reduces to a linear factor of the form 1+z, the multivariate situation becomes more exciting as now quotient ideals in the ring of Laurent polynomials are involved, a ring that is fundamentally different from the ring of polynomials. In this talk I want to introduce some of these less freightening than natural connections and point out some consequences of this nice connection between analysis and algebra.

Prof. Dr. %maroon%'''Martin Burger'''%% (Universität Münster) gave [[http://www.mathematik.uniosnabrueck.de/kolloquium.html Kolloquium]] talk on Nov. 18 2009 on %green%''Medical Mathematics — A Future Key Discipline''%%
%abbox% %maroon%Abstract%%: In this talk I will discuss some aspects in the interplay of mathematics and medicine with particular focus on two examples from cardiology: (i) The quantitative diagnosis of perfusion with PET techniques, (ii) the characterization and therapy of cardiac arrythmias using ECGI techniques. I shall discuss some mathematical questions arising from those imaging and inversion tasks, related to modelling, analysis, and numerical simulation. Moreover, I will highlight the interactive nature between the formulation of diagnostic targets and (to a lower extent) therapeutic strategies, and the formulation and solution of mathematical problems. This work is based on several collaborations with and data from the University Hospital Muenster and the European Institute for Molecular Imaging, Muenster.

Dr. %maroon%'''Philipp Grohs'''%% (Vienna and Graz University of Technology) gave a talk on Oct. 19 2009 on %green%''Some new results in Shearlet theory''%%
%abbox% %maroon%Abstract%%: The first part of the talk focuses on the question of which conditions
a function {$\psi$} needs to satisfy in order to qualify as a shearlet.
By this we mean that it must be possible to represent any
{$L^2$}function {$f$} by sheared and scaled translates of {$\psi$} and that
the decay rate of the shearlet coefficients gives precise information
about the microlocal behavior of {$f$}. We show that essentially all
that is needed for {$\psi$} to fulfill these requirements are sufficiently many
anisotropic vanishing moments.
In the second part we adress the problem of combining the shearlet
concept with the concept of Multiresolution Analysis. Our approach is
to construct 'shearlet scaling functions' which satisy a refinement
relation adapted to the shearlet structure. This construction utilizes
a novel kind of subdivision procedure. (''Oberseminar, Mon. 19.10.2009 at 16:15, Uni. Osnabrück, Building 69/E15'') %%
