Automorphism Groups of Riemann Surfaces

 Abstract

 Riemann surfaces are classical mathematical objects which are still a hot topic of re search today. They are analytic structures which are also manifolds, and there is a natural group action on them (in the form of automorphism groups). As such, we can use analysis, topology, and algebra to study them. This talk will introduce Riemann surfaces and their automorphism groups, focusing on the algebraic side. We will end with some recent re search on these automorphisms, as well as applications to Jacobian varieties. This research includes work by, and with, several Chilean colleagues.
