Oberseminar Differentialgeometrie: Thibaut Delcroix (Universität Montpellier), Vortrag: Canonical metrics in weighted Kähler geometry

Abstract: In weighted Kähler geometry, we consider Kähler manifolds equipped with a torus action, and a fixed positive function on the moment polytope. I will i...

Wilhelm Killing Kolloquium: Prof. Dr. Michael Dumbser (University of Trento): A simple and general framework for the construction of exactly div-curl-grad compatible discontinuous Galerkin finite element schemes on unstructured simplex meshes

We introduce a new family of discontinuous Galerkin (DG) finite element schemes for the discretization of first order systems of hyperbolic partial differential...

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...

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...

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. In these models, vertices of a graph hold an opinion, taking for instance valu...

Joao Lobo Fernandes (Karlsruher Institut für Technologie): Stable moduli spaces of odd-dimensional manifold triads

Abstract: The cohomology ring of moduli spaces of manifolds is an important object in geometric topology, as it classifies characteristic classes of manifold bu...
