speaks on

Group actions on buildings

Abstract. We describe the type (in the sense of von Neumann) of certain group actions on buildings. We begin with the simple case of a free group acting on a tree. Our approach will be more geometrical than analytical; a good undergraduate course in algebra should be the only prerequisite.
