The dynamical Cuntz semigroup: some categorical aspects Perera, Francesc


This talk will report on joint work in progress with Joan Bosa, Jianchao Wu, and Joachim Zacharias. A notion of action by a group on a Cuntz semigroup will be defined, and the various categories involved described. We also define a semigroup that encodes the action and indicate its role in the description of purely positive elements in certain crossed products.
