Koen van den Dungen (Bonn): Index theory and spectral flow of Toeplitz operators. Oberseminar C*-Algebren.

Dirac-Schrödinger operators (or Callias-type operators) are given by Dirac-type operators on a smooth manifold, together with a potential. I will describe a gen...

Xiaohao Ji (FU Berlin): Stochastic Hartree NLS in 3d coming from a Many-Body Quantum System with White Noise Potential

In this talk, we will discuss about the global well-posedness for the multiplicative stochastic Hartree NLS in 3d with Hartree nonlinearity. The main tools are ...

Tea Seminar: Paul Philippe (Universität Münster): Gallery models in buildings and generalizations

Gallery models in buildings provide combinatorial models to approach geometric or representation theoretic problems involving reductive groups and their loop gr...

Anar Abdullayev (Uni Münster): Reduced basis methods for inexact solves in H_2-optimal model reduction

We introduce an inexact IRKA framework for $\mathcal{H}_{2}$-optimal model reduction of large-scale linear time-invariant SISO systems. In this approach, the co...

Lutz Hille: On Schur Functors (Research Seminar on Geometry, Algebra and Topology: Moduli Spaces of Complex Curves)

Emma Brink (Universität Bonn): Thom spectra in (global) equivariant homotopy theory

Abstract: Many equivariant phenomena arise uniformly in families of groups, giving rise to so-called global objects. Such objects can be efficiently described u...

Katrin Tent: Universal homogeneous hyperbolic spaces.

In this talk I will explain how to obtain a hyperbolic analog of the Urysohn space and discuss some related problems.

Wilhelm Killing Kolloquium: Prof. Dr. Nina Gantert (TU München): Consensus and Disagreement in Opinion Dynamics

We explain some models coming from mathematical modelling of social interactions.
