DESCRIPTION:Title: <a href="https://researchseminars.org/talk/SFUQNTAG/85/
 ">(postponed) Automorphism groups of Riemann surfaces</a>\nby Jen Paulhus 
 (Grinnell College) as part of SFU NT-AG seminar\n\nLecture held in K-9509.
 \n\nAbstract\n(postponed)\n\nA well-known result on compact Riemann surfac
 es says that the automorphism group of any such surface is a finite group 
 of bounded size (based on the genus of the surface).  Additionally\, the R
 iemann-Hurwitz formula gives us an expectation for when a particular group
  should be the automorphism group of a Riemann surface of a particular gen
 us. There has been a lot of work over the last 20 years to classify which 
 groups show up for a given genus. \n\nThis talk will introduce the core id
 eas in the field\, explain the connection with curves over number fields\,
  and talk about recent results to classify groups which are indeed automor
 phisms in just about every genus they should be.  We’ll also make a surp
 rising connection to simple groups.\n
