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...

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: 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...
