皆様
(クロスポストをご容赦ください。)

直前のご案内になってしまいましたが、明日(8/18)
北京大学のXiaomeng Xuさんのセミナーを開催いたします。

日時 8月18日 10:00--12:00
場所: 京都大学数理研本館006号室
講演者: Xiaomeng Xu (Peking University)
タイトル: On the WKB approximation and the Riemann-Hilbert problem of meromorphic linear systems with Poncaré rank 1.  
アブストラクト: This talk first gives an introduction to the Stokes matrices of meromorphic linear systems with Poncaré rank 1. It then express explicitly the Stokes matrices via the leading asymptotics of solutions of the associated isomonodromy equation at a critical point. Such an expression of Stokes matrices can be understood as a perfect analytic model from various perspective. In particular, the expression is used to study the WKB approximation of the Stokes matrices, and its relation with Cauchy interlace inequalities, the spectral network and so on. If time allows, the talk discusses the WKB approximation and Stokes matrices of a quantum meromorphic linear systems with Poncaré rank 1, with a relation to quantum groups and crystal basis. 

御関心をお持ちの方のご参加を歓迎いたします。
