On ideals in De Morgan residuated lattices

Liviu-Constantin Holdon (2018)

Kybernetika

Similarity:

In this paper, we introduce a new class of residuated lattices called De Morgan residuated lattices, we show that the variety of De Morgan residuated lattices includes important subvarieties of residuated lattices such as Boolean algebras, MV-algebras, BL-algebras, Stonean residuated lattices, MTL-algebras and involution residuated lattices. We investigate specific properties of ideals in De Morgan residuated lattices, we state the prime ideal theorem and the pseudo-complementedness...

A short note on lattices allowing disjunctive reasoning.

Similarity:

This short note shows that the scheme of disjunctive reasoning, , not , does not hold neither in proper ortholattices nor in proper de Morgan algebras. In both cases the scheme, once translated into the inequality , forces the structure to be a boolean algebra.
