Graduate Seminar (Bielefeld)

Location
We meet in T2-226 (Bielefeld University) on Mondays at 2:15 pm.

Schedule Sommersemester 2024
  • 08.04. Rebekka Strathausen – Theta lifts and Maass forms
  • 15.04. Sarah Meier – Hecke Operators on the Bruhat-Tits Building
  • 22.04. Tomas Reunbrouck – Counting with p-adic analysis
  • 29.04. Bianca Marchionna – Are tdlc groups accessible?
  • 06.05. Elisa Hartmann – Geometric intuition of type FPm
  • 13.05. no seminar
  • 20.05. no seminar
  • 27.05. Carl Mazzanti – Shafarevich maps
  • 03.06. Moritz Hartlieb (Universität Bonn) – Special subvarieties of moduli spaces
    In 1987, Coleman conjectured that for sufficiently large genus, there are only finitely many curves admitting complex multiplication on their Jacobians. By the André-Oort conjecture, recently proven by Tsimerman, this is equivalent to the non-existence of positive-dimensional special subvarieties in the moduli space of curves. I will recall known counter-examples in low genus and discuss an analogous question for the moduli space of cubic threefolds.
  • 10.06. no seminar
  • 17.06. Daniel Echtler (HHU Düsseldorf) – Profinite Properties and Galois Cohomology
    In recent years the study of profinite properties grew to a reasonably sized topic in group theory. In this talk I want to give a brief introduction to the topic. Moreover I want to discuss how Galois cohomology and algebraic groups can be used in this context to give some counter examples.
