Johannes Schmidt-Hieber, Twente: Towards a statistical foundation of deep learning (Oberseminar Mathematische Stochastik)

Recently a lot of progress has been made in the theoretical understanding of deep learning.

David Bradley-Williams (HHU Düsseldorf): Spherically complete models of hensel minimal fields

A valued field is called maximal if it admits no proper immediate extentions (having the same residue field and value group). Krull observed that every valued...

Kolloquium Wilhelm Killing: Dr. Dawid Kielak (Bielefeld): Three-manifolds, Thurston's insights and a little algebra

I will survey the current state of our knowledge of 3-manifolds, focusing on what we have learned from Thurston, and on the relatively recent breakthroughs. I w...

Philip Dowerk (Dresden): Analogies between finite- and infinite-dimensional unitary groups. Oberseminar C*-Algebren.

Rachael Boyd (MPI Bonn): Embedding spaces of Hopf links. (Oberseminar Topologie)

We show that the connected component of the embedding space of links in R^3 containing the split union of m Hopf links and n unknots is homotopy equivalent to a...

Oberseminar Differentialgeometrie: Maximilian Stegemeyer (Würzburg): Endpoint geodesics in extrinsic symmetric spaces

"In this talk the geodesic equation in symmetric spaces is considered as a boundary value problem. We show that in extrinsic symmetric spaces this problem ca...

Oberseminar Differentialgeometrie: Jason Ledwidge (Tübingen): The structure of non-compact shrinking Ricci solitons via heat kernel estimates

Ricci solitons are solutions to the Ricci flow modulo a diffeomorphism, and arise as singularity models for the Ricci flow. In this talk, we will outline the pr...
