SpeakerProf.Michael Zieve, University of Michigan

Time: 2016-12-07 10:00-11:00

Room 1518, School of Mathematical Sciences 


Detail: The two main geometric invariants of a complex rational function are its monodromy group and ramification type.  I will explain the progress made in 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 applications to number theory, analysis, topology, and dynamics.
