Antrittsvorlesung von Prof. Dr. Martin Huesmann: Moving Stones, Model Uncertainty, and Matching Couples

The theory of optimal transport has developed into a powerful tool for the analysis and geome-try of PDEs and singular spaces. In this talk, I show how it can b...

Antrittsvorlesung von JProf.'in Dr. Theresa Simon: Nonlocal isoperimetric problems

The classical isoperimetric problem, which has been known since antiquity, asks for a body with the least surface area given its volume. Comparatively recently,...

Björn Gebhard (Universität Leipzig): On the Rayleigh-Taylor instability

We consider the inhomgeneous incompressible Euler equations describing two fluids with different constant densities under the influence of gravity. Initially ...

Oberseminar Topologie: Akhil Mathew (University of Chicago, U.S.A.): Syntomic complexes and TC of regular rings.

Bhatt--Morrow--Scholze constructed a motivic filtration on the topological cyclic homology of an animated ring whose associated graded quotients (called syntomi...

Christopher Deninger: Primzahlen und Knoten (Ringvorlesung)

Im Vortrag geht es um merkwürdige Analogien zwischen der Knotentheorie und der Theorie der Primzahlen, die bei der Geometrisierung der Zahlentheorie durch die étale Topologie auftreten.

Stefank Junk, Tohoku University, Japan: Fluctuations for partition function of directed polymers beyond the L^2 phase

The directed polymer model describes random paths under the influence of a space-time random environment.

Andre Nies (Auckland): Meet groupoids and the Borel complexity of the isomorphism relation between oligomorphic groups

A meet groupoid is an algebraic structure that is a groupoid and at the same time a meet semilattice with least element. The cosets of open subgroups of a topol...
