β¦ Synopsis
It is shown that any subvariety Y of the variety of bounded distributive lattices with a quantifier, as considered by Cignoli (1991), contains either uncountably or finitely many quasivarieties depending on whether Vcontains the 4-element bounded Boolean lattice with a simple quantifier. It is also shown that, in the former case, the quasivarieties contained in Yform a lattice which fails to satisfy every nontrivial lattice identity while, in the latter case, they form a chain of length < 3.

In this note we introduce and study algebras ( L , V, A, 1, 0,l) of type (2,2,1,1,1) such that ( L , V, A , 0 , l ) is a bounded distributive lattice and -,is an operator that satisfies the conditions -,(a V b ) = -,a A -,b and -0 = 1. We develop the topological duality between these algebras and Pr
An ordered compact space is a compact topological space X, endowed with a partially ordered relation, whose graph is a closed set of X x X (of. [4]). An important subclass of these spaces is that of Priest/ey spaces, characterized by the following property: for every x, y ~X with x~y there is an inc
