 ">Automorphism groups of Riemann surfaces</a>\nby Jen Paulhus (Grinnell Co
 llege) as part of SFU NT-AG seminar\n\n\nAbstract\nA well-known result on 
 compact Riemann surfaces says that the automorphism group of any such surf
 ace is a finite group of bounded size (based on the genus of the surface).
  Additionally\, the Riemann-Hurwitz formula gives us an expectation for wh
 en a particular group should be the automorphism group of a Riemann surfac
 e of a particular genus. There has been a lot of work over the last 20 yea
 rs to classify which groups show up for a given genus. \n \nThis talk will
  introduce the core ideas in the field\, explain the connection with curve
 s over number fields\, and talk about recent results to classify groups wh
 ich are indeed automorphisms in just about every genus they should be.  We
 ’ll also make a surprising connection to simple groups.\n
