LAGOON: Leicester Algebra and Geometry Open ONline
These seminars are organized by Frank Neumann and Sibylle Schroll, University of Leicester
This Algebra and Geometry webinar series has a strong focus on Representation Theory and Algebraic Geometry and their many interactions covering topics such as homological mirror symmetry, stability conditions, derived categories, dg-categories, Hochschild cohomology of algebras, moduli spaces and algebraic stacks, derived algebraic geometry etc.
These seminars take place on Thursday at 13:00-14:00 (BST)
Registration will close at 11.00 each Thursday.
You will be sent a link to the Zoom meeting on Thursday morning
These seminars are recorded. All recordings can be found here.
Future speaker details can be found her.

Title: Geometry of the Associative Yang-Baxter equation
Abstract: I will describe the connection, discovered jointly with Yanki Lekili, between Associative Yang-Baxter equation (AYBE) and pairs of 1-spherical objects in A-infinity categories. I will then explain how such pairs arise from noncommutative orders over singular curves, in particular, how to get all nondegenerate trigonometric solutions of the AYBE in this way. If time allows, I will talk about the Lie analog of this story for the classical Yang-Baxter equation.

Title: Euler numbers of Hilbert schemes of points on simple surface singularities and quantum dimensions of standard modules of quantum affine algebras
Abstract: Balazs explained his conjecture with Gyenge and Nemethi on Euler numbers of Hilbert schemes on June 4. I proved it by showing that quantum dimensions of standard modules of quantum affine algebras are always 1. This remarkable property is the simplest case of a conjecture on quantum dimensions of Kirillov-Reshetikhin modules proposed by Kuniba in 93, which is still open for E7,8 in general. In this talk, I will emphasize on representation theoretic aspects to minimize overlaps with Balazs' talks
