Julien Melleray: The simplex of invariant measures of a minimal homeomorphism

Place: Fields Institute (Room 210) Date: November 20th, 2015 (14:00-15:00) Speaker: Julien Melleray Title: The simplex of invariant measures of a minimal homeomorphism Abstract:  (joint work with Tomás Ibarlucia) We give a characterization of all simplices of probability measures on a Cantor space X which may be realized as the simplex of all invariant probability measures for some minimal homeomorphism g of X. continue reading…
