Fabian Hebestreit (Universität Bielefeld): Homology manifolds and euclidean bundles

Abstract: It is a curious fact of life in geometric topology, that the classification of closed manifolds by surgery theory becomes easier as one passes from ...

Abdulwahab Mohamed (University of Edinburgh): Rough Uhlenbeck Compactness with Application to 2D Yang-Mills Measure

We introduce the concept of rough additive functions, which extends rough paths theory to line integrals of distributional 1-forms. In the context of gauge theo...

Thomas Stucker (ETH Zürich, Schweiz): Quasinormal modes for the Kerr black hole

The late-time behavior of solutions to the wave equation on Kerr spacetime is governed by inverse polynomial decay. However, at earlier time-scales, numerical s...

Shuoxing Zhou (Paris): Noncommutative topological boundaries and amenable invariant intermediate subalgebras. Oberseminar C*-Algebren.

As an analogue of topological boundary of discrete groups $\Gamma$, we define the noncommutative topological boundary of tracial von Neumann algebras $(M,\tau)$...

Lena Schmedt (Uni Münster): Total variation regularized optimization solved by the Frank Wolfe algorithm

To find solutions of total variation (TV) regularized optimization problems, we want to make use of the Frank Wolfe (FW) algorithm. Therefore, we analyze what t...
