Exact Borel subalgebras, good quotients and good subalgebras

2023-03-22

Speaker: Teresa Conde (Univ. of Stuttgart, Germany)

Exact Borel subalgebras of strandardly stratified algebras emulate the role of classic Borel subalgebras of complex semi-simple Lie algebras. Up to Morita equivalence, every standardly stratified algebra has an exact Borel subalgebra. By their recursive nature, standardly stratified algebras...

Normal forms in Poisson geometry

2023-03-29

Speaker: Ioan Marcut (Univ. Nijmegen, Netherlands)

This is an introductory talk to Poisson geometry, with a focus on normal forms for Poisson structures. First, we will discuss Weinstein's Splitting theorem and the linearization problem around points, including Conn's theorem. Then I will discuss some of the problems I have worked on:...

A new characterization of internal groupoids

2023-05-30

Speaker: Nelson Martins-Ferreira (IP Leiria)

In this talk we will present a new characterization of internal groupoids using involutive-2-links. An involutive-2-link consists of a single morphism equipped with a pair of interlinked involutions on its domain [1]. We will see that there exists a full and faithful functor from the...
