Extensions of semigroups and Banach modules E. V. Lipacheva Kazan State Power Engineering University
Abstract: We consider the normal extensions of semigroups. The reduced semigroup $C^$-algebras are associated with these extensions. We study the structure of a Banach module on the underlying space of the reduced semigroup $C^$-algebra defined for a semigroup that is an extension of another semigroup by a finite group Keywords: cancellative semigroup, normal extension of semigroup, reduced semigroup $C^$-algebra, Banach module, free Banach module.* Website: https://zoom.us/j/91819779435?pwd=K1llRzUyV1VCclMzQjRtUEFpMzhYQT09 ^* Zoom conference ID: 918 1977 9435 , password: 633421
