GEOMETRY AND ITS INTERFACES
The proceedings of the virtual 2022 International Congress of Mathematicians has appeared. It can be freely downloaded. Our contribution with title “Enhanced mirror symmetry for Langlands dual Hitchin systems” can be found here. Its abstract is: “The first part of this paper is a survey of mathematical results on mirror symmetry phenomena between Hitchin systems Read More …
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 …
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.
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 …
Michael Gröchenig, DPhil (=PhD) student in Oxford 2009-2013, received a 2024 New Horizons prize in Mathematics – the Breakthrough prize for early career researchers – “For contributions to the theory of rigid local systems and applications of p-adic integration to mirror symmetry and the fundamental lemma.” Congratulations to Michael!
There will be an Arbeitsgemeinshcaft in Oberwolfach 31 Mar- 5 April 2024 on the two recent proofs of the P=W conjecture. More information here: https://www.mfo.de/occasion/2414
Journal of the European Mathematical Society is the flagship journal of the EMS. It publishes papers of outstanding quality and interest, according to the highest international standards. Papers can be submitted here.
A new journal, Moduli of the Compositio Foundation accepts submissions here. “Moduli provides a new forum for significant new results on all aspects of moduli theory or related mathematics, including but not restricted to techniques from: algebraic, differential and arithmetic geometry; combinatorics; dynamical systems; gauge theory; geometric analysis; geometric group theory; pure mathematics inspired by physics; Read More …
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 …
