Paper by summer intern Vladyslav Zveryk

In a new paper on arxiv: “Dynkin automorphisms actions on Gaudin algebras” 2022 ISTern and 2023 ISTA summer intern Vladyslav Zveryk gives a proof of the twining conjecture on big algebras. “In this paper, we study the action of a Dynkin automorphism σ of a simple Lie algebra 𝔤 on the generalized Gaudin algebras. In particular, we show isomorphisms Read More …

Bourbaki seminar on P=W

The next Bourbaki seminar on 18 November at 14:30 will feature the talk Victoria Hoskins: “Two proofs of the P = W conjecture, after Maulik–Shen, Hausel–Mellit–Minets–Schiffmann“ The talk could be followed live at this link.

New paper on big algebras

The paper “Big algebras” is in the arxiv. Here is the abstract: “Here we announce the construction and properties of a big commutative subalgebra of the Kirillov algebra attached to a finite dimensional irreducible representation of a complex semisimple Lie group. They are commutative finite flat algebras over the cohomology of the classifying space of Read More …

Videos and slides of minicourse in Madrid available

Conference: The Hitchin system, Langlands duality and mirror symmetry, ICMAT Madrid, April 2023 Minicourse: Mirror symmetry and big algebras After surveying some mirror symmetry phenomena in the geometry of Langlands dual Hitchin systems, we will model the Hitchin system on cominuscule upward flows by the equivariant cohomology of cominuscule flag varieties like the Grassmannian. Then Read More …
