Inversion of matrices over a pseudocomplemented lattice

Journal of Mathematical Sciences, 2007
We compute the greatest solutions of systems of linear equations over a lattice (P, ≤). We also present some applications of the results obtained to lattice matrix theory. Let (P, ≤) be a pseudocomplemented lattice with $$\widetilde0$$ and

The Lattices of Kernel Ideals in Pseudocomplemented De Morgan Algebras

Order, 2016
A pseudocomplemented De Morgan algebra is a bounded distributive lattice \(L\) endowed with two unary operations, \(\circ\) and \(\ast\), such that \((L,\circ)\) is a De Morgan algebras and \((L,\ast)\) a distributive p-algebra. Pseudocomplemented De Morgan algebras form an equational class \textbf{pdM}. A kernel ideal \(I\) of \(L\) in \textbf{pdM} is

On varieties defined by pseudocomplemented nondistributive lattices

Publicationes Mathematicae Debrecen, 2003
A lattice \(L\) with \(1\) is called sectionally complemented if every interval \([a,1]\) is pseudocomplemented. On such lattices, a new operation \(\circ\) is introduced by the rule that \(x\circ y\) is the pseudocomplement of \(x\vee y\) in \([y,1]\). It is known that the resulting algebras form a variety. In the present paper the authors investigate

The Lattice of Kernel Ideals of a Balanced Pseudocomplemented Ockham Algebra

Studia Logica, 2012
In this note we shall show that if L is a balanced pseudocomplemented Ockham algebra then the set $${\fancyscript{I}_{k}(L)}$$ of kernel ideals of L is a Heyting lattice that is isomorphic to the lattice of congruences on B(L) where $${B(L) = \{x^* | x \in L\}}$$ .

Pseudocomplemented lattice effect algebras and existence of states

Information Sciences, 2009
The author studies pseudocomplemented lattice effect algebras. In particular, it is shown that the set of sharp elements in a pseudocomplemented lattice effect algebra forms a Boolean algebra (with the inherited pseudocomplementation as an orthocomplementation) and that every pseudocomplemented complete atomic lattice effect algebra admits a state.

Demi-pseudocomplemented lattices: principal congruences and subdirect irreducibility

Algebra Universalis, 1990
In this (essentially self-contained) paper the author continues his earlier investigations on demi-p-lattices [J. Symb. Logic 52, 712-724 (1987; Zbl 0628.06011)]. In Section 2, definitions and some new characterizations of demi-p-lattices, almost p-lattices and p-lattices are presented.

On the Decision Problem of the Congruence Lattices of Pseudocomplemented Semilattices( )

1977
Publisher Summary This chapter focuses on the decision problem of the congruence lattices of pseudocomplemented semilattices. The essential undecidability of the theories of closure algebras, Brouwerian algebras, the algebras of bodies, the algebras of convexity, and the semi-projective algebra are discussed in the chapter.
