GRK-Seminar Sommersemester 2026

RTG Seminar Summer Term 2026

The Thursday morning seminar (10:15-11:45 in WSC-N-U-3.05) will be the “Research Training Group Seminar” where members of the RTG (PhD students, post-docs,…) present their results. Sometimes, we also have speakers from other places. Depending on the number of speakers and on the proposed topic, a speaker could use one or two sessions.

Abstracts

Wieslawa Niziol. Duality theorems in p-adic analytic geometry

I will discuss duality theorems for p-adic geometric pro-etale cohomology of partially proper rigid analytic varietes. The first two lectures will address the dualities on the Fargues-Fontaine curve by reducing them to coherent dualities, the remaining two — will descend these dualities to the world of Topological Vector Spaces. This is a joint work with Pierre Colmez and Sally Gilles.

Davide Gori: Modular Compactifications of $M_{g,n}$ via Cluster Algebras

We discuss the first steps of the Minimal Model Program and the Hassett-Keel program for the Deligne-Mumford compactification of $M_{g,n}$. In this context, we construct several new compactifications arising as good moduli spaces of stacks of curves with $A$-type singularities, realized as $\Theta$-semistable loci with respect to line bundles on a suitable stack. Varying the line bundle yields an involved wall-crossing picture in the space of stability conditions, which can be described combinatorially using cluster algebras.
