Principal congruences of pseudocomplemented distributive lattices [PDF]

open access: yesProceedings of the American Mathematical Society, 1973
Principal congruences of pseudocomplemented distributive lattices are characterized. This characterization is used to give a new proof of the congruence extension property and to show that the meet of two principal congruences is always principal in an equational class of pseudocomplemented distributive lattices if and only if the class is a subclass ...

Varieties of Demi‐Pseudocomplemented Lattices

open access: yesMathematical Logic Quarterly, 1991
The authors present a solution to the problem of desribing the structure of the lattice of subvarieties of the variety of demi \(p\)-lattices, and in particular of almost \(p\)-lattices. The main purpose is to present an infinite poset \(P_ 0\) whose Hasse diagram is completely described by the following property: The lattice of subvarieties of the ...

Implications in pseudocomplemented and Stone lattices

open access: yes
Two kinds of the connective implication are introduced as term operations of a pseudocomplemented lattice. It is shown that they share a lot of properties with the intuitionistic implication based on Heyting algebras. In particular, if the pseudocomplemented lattice in question is a Stone lattice then the considered implications satisfy some kind of ...

Median filters of pseudocomplemented distributive lattices

open access: yesDiscussiones Mathematicae - General Algebra and Applications
Summary: Coherent filters, strongly coherent filters, and \(\tau\)-closed filters are introduced in pseudo-complemented distributive lattices and their characterization theorems are derived. A set of equivalent conditions is derived for every filter of a pseudo-complemented distributive lattice to become a coherent filter.

Sectionally pseudocomplemented posets [PDF]

open access: yes, 2021
The concept of a sectionally pseudocomplemented lattice was introduced in Birkhoff (1979) as an extension of relative pseudocomplementation for not necessarily distributive lattices.
