Spring semester 2022

Constructing moduli spaces via Geometric Invariant Theory

Hybrid joint seminar between Università degli Studi di Milano and JGU Mainz

Description: This is a joint seminar aimed to master and PhD students. The goal of the seminar is to learn how to construct moduli spaces using Geometric Invariant Theory.

The meetings will start on Monday 9 May 2022, and they will be held on mondays, 12:15--13:4. Below you will find the schedule.

The credential to access the meeting will be communicated short in advance via email.

If you want to participate, please contact the organizers.



Organizers: Dino Festi (Milano), Manfred Lehn (Mainz).
