In this paper, we investigate the variety RDP of regular double p-algebras and its subvarieties RDP n , n ≥ 1, of range n. First, we present an explicit description of the subdirectly irreducible algebras (which coincide with the simple algebras) i

Let L denote the Q-lattice of the variety $${\mathcal {V}}$$ of lattices, i.e. the lattice of quasivarieties that are contained in $${\mathcal {V}}$$ . Let F denote the free lattice in $${\mathcal {V}}$$ with $$\omega $$ free generators and let Q(F)

In this paper, we investigate the varieties $\mathbf M_n$ and $\mathbf K_n$ of regular pseudocomplemented de Morgan and Kleene algebras of range $n$, respectively. Priestley duality as it applies to pseudocomplemented de Morgan algebras is used. We c

The lattice of varieties of quasi-Stone algebras ordered by inclusion is an $${\omega+1}$$ chain. It is shown that the variety $${\mathbf{Q_{2,2}}}$$ (of height 13) is finite-to-finite universal (in the sense of Hedrlin and Pultr). Further, it is sho

We will address these questions in order, and provide good partial answers, especially for finite lattices which are bounded homomorphic images of a free lattice. Recall that a finite lattice is bounded if and only if it can be obtained from the one

A topological space X is said to be submaximal if every dense subset of X is open. In this paper, descriptions of submaximal spectral spaces and Stone submaximal spaces are given. Throughout this paper a number of illustrative examples are given.

Let V be a non-trivial variety of bounded distributive lattices with a quantifier, as introduced by Cignoli in [7]. It is shown that if V does not contain the 4-element bounded Boolean lattice with a simple quantifier, then V contains non-isomorphic

A semigroup S is said to have the ideal retraction property provided each of its ideals is the image of an idempotent endomorphism of S. The main result of this work is a characterization of those bands which have the idempotent retraction property.

The Birkhoff-Maltsev problem asks for a characterization of those lattices each of which is isomorphic to the lattice L(K) of all subquasivarieties for some quasivariety K of algebraic systems. The current status of this problem, which is still open,
