Title:  Geometric invariants of rational functions

Abstract:  Geometric invariants of rational functions The two main geometric invariants of a complex rational function are its monodromy group and ramification type. I will explain the progress made during the past 125 years towards determining all possibilities for these invariants, including contributions by Hurwitz, Zariski, Thom, Guralnick, Thompson, and Aschbacher. I will also present several applications. This talk will be accessible to everyone, and students are invited to attend.
