## Stone style duality for distributive nearlattices.(English)Zbl 1301.06030

Summary: The aim of this paper is to study the variety of distributive nearlattices with greatest element. We will define the class of $$N$$-spaces as sober-like topological spaces with a basis of open, compact, and dually compact subsets satisfying an additional condition. We will show that the category of distributive nearlattices with greatest element whose morphisms are semi-homomorphisms is dually equivalent to the category of $$N$$-spaces with certain relations, called $$N$$-relations. In particular, we give a duality for the category of distributive nearlattices with homomorphisms. Finally, we apply these results to characterize topologically the one-to-one and onto homomorphisms, the subalgebras, and the lattice of the congruences of a distributive nearlattice.
