Speaker: Bin Zhang, Sichuan University

Abstract: This is joint work with L. Guo, S. Paycha. In this talk, we will use the geometry of convex polyhedral cones to study a large class of multivariate meromorphic germs, namely those with linear poles, which naturally arise in various contexts in mathematics and physics. By analyzing the conical structure of the linear poles, we develop a Laurent theory of this class of germs, where the key issue is the uniqueness of such expansions. We will give some applications of these Laurent expansions in the end.
