Mathematical Sciences Seminar for Master's Students

Ribbon Graphs and Riemann Surfaces – A Combinatorial View

Speaker: Yizhou Zeng, CIMS

Location: Warren Weaver Hall 1314

Date: Wednesday, October 25, 2017, 7:45 p.m.

Synopsis:

Graphs are a well-known object in the study of combinatorics. In this talk, we will introduce a specific class of graphs, ribbon graphs, to construct compact Riemann surfaces. Also, we will discuss how ribbon graphs provide us a combinatorial view on the moduli spaces.
