Classes of Semilattices Associated with an Equational Class of Lattices
Herbert S. Gaskill · Canadian Journal of Mathematics · 1973
In this paper we consider the question of whether there is a natural class of semilattices associated with a fixed equational class of lattices. We give four classes of semilattices which may be obtained from a given equational class of lattices and show that for the distributive case they coalesce into one class. An incomplete set of relations is given for the general case.
