IRTG-Seminar SS 2018

This semester we will have again two meetings with the IRTG-Seminar. The first one will take place in Saarbrücken, the second one in Kaiserslautern.

First Meeting: Wednesday, May 2^nd 2018, Saarbrücken, E2 4, Seminarraum 6.

Time	Name	Title
15:00 - 15:50	Emil Rotilio	Generic character table of finite groups of Lie type
16:00 - 16:50	Ricardo Schnur	Non-commutative rational functions and linear representations
17:00 - 17:50	Raul-Paul Epure	Derivations on Singularities

Abstracts of the first meeting

Raul's talk: The talk consists of three parts. First we give a short introduction to singularity theory. Afterwards we talk about algebraic groups and Lie algebras. In the last part we show how to connect the theory of algebraic groups and Lie algebras with singularities using the module of derivations. Using this connection we show that the in the case of quasi-homogeneous isolated hypersurface singularities information about the structure of the singularity can be read of from the derivation module of the Milnor algebra.

Second Meeting: Wednesday, July 11^th 2018, Kaiserslautern, 48-438.

Time	Name	Title
14:00-14:50	Andrea Thevis	Strata of p-Origamis
15:00-15:50	Isabel Stenger	A Homological Approach to Numerical Godeaux Surfaces
16:00-16:50	Hanieh Keneshlou	The unirationality of the Hurwitz spaces

Abstracts of the second meeting

Andrea's talk: We begin by recalling some basic definitions from topology and the theory of translation surfaces. Using these we define p-origamis which are the objects of main interest in the talk. They arise as normal covers of the torus. The goal is to classify the types of singularities of p-origamis. If time permits, I describe connections to Teichmüller theory.
