Algebra & Combinatorics Seminar

Title: Polytopes, truncations of representations and their characters
Speaker: Deniz Kus (Ruhr-University Bochum, Germany)
Date: 23 October 2020
Time: 3 pm
Venue: Microsoft Teams (online)

Generators and relations of graded limits of certain finite-dimensional irreducible representations of quantum affine algebras have been determined in recent years. For example, the representations in the Hernandez-Leclerc category corresponding to cluster variables appear to be certain truncations of representations for current algebras and tensor products are related to the notion of fusion products. In this talk, we will discuss some known results on this topic and study the characters of arbitrary truncated representations.
