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.

Deformations of path algebras of quivers with relations
Abstract: In this talk, we provide a very explicit method to describe deformations of path algebras of quivers with relations. This method is based on a combinatorial description of an L-infinity algebra constructed from Chouhy-Solotar’s projective resolution. As an application, we show that the variety associated to monomial algebras constructed by Green-Hille-Schroll is actually given by the Maurer--Cartan equation of the L-infinity algebra. This is joint work with Severin Barmeier.
