Title: “Enveloping semigroups and regionally proximal relations”
Abstract: In recent years, the study of systems of order d has drawn much interest due to their applications in the structural theory of dynamical systems, number theory, and combinatorics. One area of focus has been the algebraic properties of their enveloping semigroups. This talk will introduce the concepts of enveloping semigroups and regionally proximal relations, and explore the connections between them. Additionally, algebraic characterizations of regionally proximal relations will be presented, with an application to the study of topological characteristic factors.
