Speaker:Xiaomeng Xu


In this report, we will first give a brief introduction to the multivalued solutions of a class of differential equations with singularities and the Gelfand Zeitlin type canonical basis in representation theory. Then we will discuss how to use the asymptotic analysis of the solutions of this kind of equations to naturally get the above canonical basis and cactus group effect on it, so we will give the analysis and explanation of some discrete problems in representation theory. Our workrelieson the compactness of a class of well-knownnonlinear partial differential equations, and more understanding of such equations will produce important applications in representation theory and field theory.
