Title: Affinization of algebraic structures
Abstract: Informally and in broad terms, by affinization we mean a process which converts an algebraic structure with a nullary operation (i.e., in which a chosen element plays a special role) into one which has no nullary operations, but is such that by a free choice of any element it is retracted to the original structure. The prime example of this procedure is the conversion of groups into heaps. In this talk, we will focus mainly on the affinization of Lie algebras and Leibniz algebras. The talk is based on joint works with Tomasz Brzeziński, Ryszard Andruszkiewicz, and Brais Ramos Perez.
