A boundary quotient diagram for right LCM semigroups

Abstract

We propose a boundary quotient diagram for right LCM semigroups with property (AR) that generalizes the boundary quotient diagram for the ax+bax+b-semigroup over the natural numbers. Our approach focuses on two important subsemigroups: the core subsemigroup and the semigroup of core irreducible elements. The diagram is then employed to unify several case studies on KMS-states, and we end with a discussion on KK-theoretical aspects of the diagram motivated by recent findings for integral dynamics.
