Automorphisms of generic abelian varieties in positive characteristic

Sprecher: Prof. Dr. Eva Viehmann und Dr. Paul Philippe

In 2001, Oort conjectured that generic supersingular abelian varieties of dimension at least 2 do not have automorphisms other than \pm id. We will report on the history and the recent proof of this conjecture (by Viehmann) as well as on possible generalizations (in joint work of the speakers with Fabian Schnelle) and implications.
