DESCRIPTION:Igor Rapinchuk - Harvard University\nThe focus of this talk wi
 ll be on recent results on abstract homomorphisms between the groups of ra
 tional points of algebraic groups. I will indicate how these fit into the 
 general framework of rigidity and also give a historical perspective\, sta
 rting with results of Cartan and Schreier and van der Waerden. I will then
  discuss the main results of the landmark 1973 paper of Borel and Tits and
  address a conjecture on abstract homomorphisms that they formulated there
 . Our results settle this conjecture in several cases\; the proofs make us
 e of the notion of an algebraic ring.
