“Random matrices and our recent results”
Abstract: One of the most fundamental results underlying the theory of abelian varieties is “rigidity” — that is, that any k-scheme morphism of abelian varieties which preserves identities is actually a k-group homomorphism. This result depends crucially upon the properness of such varieties. For affine groups in general, there is no analogous rigidity statement. We will nevertheless show that such a rigidity result holds for unirational groups (which are always affine) over fields of degree of imperfection 1 which satisfy certain conditions, and discuss several implications.
