Title: Isomorphisms of Chevalley groups over rings and some applications to algebra and model theory
Abstract: We will show the recent general results about the standard description of automorphisms and isomorphisms of Chevalley groups over arbitrary commutative rings with 1.
Then we apply them to the problems of Sha-rigidity (any locally inner endomorphism is an inner automorphism) and elementary definability of Chevalley groups.
