Lie Superalgebras and categorification (Spring 2023)

Organized by Cailan Li and Alvaro Martinez. Please email me at to join the mailing list.

This is a learning seminar on superalgebras and their categorifications. The plan is to first give an overview of superalgebras and their representation theory, and then cover recent developments in the categorification program of super-stuff and related topics, as you can see in the outline below.

Outline of the seminar.

Talks will roughly be 45 minutes followed by a 5 minute break followed by 45 more minutes. Please email me at if you'd like to give a talk.

Lie superalgebras: Fundamentals

We introduce Lie superalgebras and explain the subtle differences with usual Lie algebras that occur in the theory. In particular, the presence of isotropic odd roots will force us to decorate the Dynkin diagrams associated with usual Lie algebras in order to adequately describe the structure of Lie superalgebras.
