A topological duality for monotone expansions of semilattices

Abstract

In this paper we provide a Stone style duality for monotone semilattices by using the topological duality developed in Celani2020 for semilattices together with a topological description of their canonical extension. As an application of this duality we obtain a characterization of the congruences of monotone semilattices by means of monotone lower-Vietoris-type topologies.
