Stokes structures in homotopy theory
Abstract :
Stokes structures are algebraic structures that can be extracted from the asymptotic analysis of solutions for flat bundles at singular points. Due to works of Deligne-Malgrange in dimension 1 and Mochizuki in higher dimension, they were shown to realize the irregular Riemann-Hilbert correspondence for flat bundles. In this talk, we will explain how recent advances in stratified homotopy theory provide new perspectives on Stokes structures and their moduli in any dimension. This is joint work with Mauro Porta.
Painlevé Seminar Topics
Recently, we have encountered many interesting links between differential
equations of Painlevé types and other fields of mathematics such
as algebraic geometry, non-abelian Hodge theory and topological recursion
and so on.
In this web seminar, we will organize research talks on Painlevé
equations and related topics on web (zoom), basically about once every
two or three weeks.
From September 2022, Regular time for seminar talk will be on Wednesday from 17:30--18:30 + discussion time
in JST(Japan) or 10:30--11:30 in UTC+1. We are looking forward to your participation in
the seminar. In order to get zoom access, please register through the form.
