abstract homomorphisms of algebraic groups and applications
abstract:
i will discuss several recent results on abstract homomorphisms between the groups of rational points of algebraic groups. the main focus will be on a conjecture of borel and tits formulated in their landmark 1973 paper. our result settle this conjecture in several cases; the proofs make use of the notion of an algebraic ring. i will conclude by discussing several applications to character varieties of finitely generated groups and group actions. for the pre-talk: i will recall some basic concepts from the theory of algebraic groups and outline a general philosophy for the study of rigidity phenomena between the groups of rational points of algebraic groups.
