报告摘要:

    This talk gives an introduction to the Stokes phenomenon of meromorphic linear systems of ordinary differential equations, and its isomonodromy deformation. It then discusses three aspects of Stokes phenomenon: on the analysis side, it gives an explicit formula of Stokes matrices via the asymptotics of the associated isomonodromy equations; on the algebraic side, it gives a realization of crystal basis (of type A Lie algebras); in the end, on the geometric side, it conjecturally relates the WKB approximation of Stokes matrices with the periods on the associated spectral curves, and gives a realization of cluster algebras on certain double Bruhat cells using the geometry of Hitchin systems. The last part is a work in progress with Anton Alekseev and Yan Zhou.
