Rigidity of actions on algebraic spaces

Jeudi 26 mars 2009 14:00-15:00 - Gorodnik Alex - Bristol

Résumé : We survey some of the known rigidity results which show that objects defined in the measurable category are of algebraic origin and discuss a joint work with Bader, Furman, and Weiss that classifies measurable isomorphisms and factors for ergodic actions on homogeneous varieties.
