Finite pseudocomplemented lattices and ‘permutoedre’

open access: yesDiscrete Mathematics, 1993
The authors summarize, without proof, their results on the structure of finite meet pseudocomplemented, meet and join pseudocomplemented, and pseudocomplemented and complemented lattices. Some sample results are as follows. A finite lattice is a meet pseudocomplemented lattice if and only if each atom has a meet pseudocomplement, and a finite meet ...

Free-decomposability in Varieties of Pseudocomplemented Residuated Lattices

open access: yesStudia Logica, 2011
A pseudocomplemented residuated lattice is a bounded residuated lattice \(\mathbf A=\langle A, \ast, \rightarrow,\vee, \wedge, \mathbf 0, \mathbf 1\rangle\) satisfying the equation: \(x \wedge \neg x= \mathbf 0\), where \(\neg x:=x \rightarrow \mathbf 0\), for all \(x \in A\).

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.

The Structure of Pseudocomplemented Distributive Lattices. I: Subdirect Decomposition [PDF]

open access: yesTransactions of the American Mathematical Society, 1971
In this paper all subdirectly irreducible pseudocomplemented distributive lattices are found. This result is used to establish a Stone-like representation theorem conjectured by G. Grätzer and to find all equational subclasses of the class of pseudocomplemented distributive lattices.

The Structure of Pseudocomplemented Distributive Lattices. II: Congruence Extension and Amalgamation [PDF]

open access: yesTransactions of the American Mathematical Society, 1971
This paper continues the examination of the structure of pseudocomplemented distributive lattices. First, the Congruence Extension Property is proved. This is then applied to examine properties of the equational classes

ON n-MIXED PRODÜCT OF PSEUDOCOMPLEMENTED DISTRIBUTIVE LATTICES

open access: yesDemonstratio Mathematica, 1986
The author defines for a finite family of pseudocomplemented distributive lattices what she calls a mixed product. She then considers the variety generated by all such mixed products, and obtains a finite base for this variety.
