Title: Group-equivariant versions of the Radon-Nikodym property
By Michal Doucha (Institute of Mathematics of the Czech Academy of Sciences)
Abstract: I will present several variants of closely related Banach space notions such as the Radon-Nikodym property, the Bishop-Phelps property, dentability, etc., defined in the presence of a continuous action of a topological group on a given Banach space by linear isometries. While in the classical case these notions are equivalent, in the presence of a group action it depends on the group. This is work in progress jointly with Sheldon Dantas, Mingu Jung and Tomáš Raunig.
