Automorphism groups in algebraic geometry

Speaker: Michel Brion

Date: Fri, Mar 10, 2017

Location: PIMS, University of British Columbia

Conference: PIMS/UBC Distinguished Colloquium

Subject: Mathematics, Algebraic Geometry

Class: Scientific

Abstract:

The talk will first present some classical results on the automorphisms of complex projective curves (or alternatively, of compact Riemann surfaces). We will then discuss the automorphism groups of projective algebraic varieties of higher dimensions; in particular, their "connected part" (which can be arbitrary) and their "discrete part" (of which little is known).
