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...

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:...

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...
