Oberseminar p-adische Arithmetik: Local cohomology of flag varieties and modular curves: Siqi Yang: Modular forms and p-adic modular forms

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...

Oberseminar Differentialgeometrie: Fernando Galaz Garcia (Universität Warwick), Vortrag: Torus actions and twisted suspensions

Abstract: Manifolds equipped with torus actions are a central object of study in geometry and topology. In this talk, I will discuss the topological structure o...

Mittagsseminar zur Arithmetik: Nataniel Marquis (Münster): Mod p local Langlands correspondance : GL2(Qp) knowledges, hopes beyond.

The p-adic local Langlands aims to link representations of G(K), where G is a reductive group and K a p-adic local fields, with p-adic coefficients, and represe...

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...

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...

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.
