On Implicative and Positive Implicative GE Algebras

open access: yesBulletin of the Section of Logic, 2023
GE algebras (generalized exchange algebras), transitive GE algebras (tGE algebras, for short) and aGE algebras (that is, GE algebrasverifying the antisymmetry) are a generalization of Hilbert algebras. Here some properties and characterizations of these algebras are investigated.

On an Intuitionistic Fuzzy Form of the Goguen’s Implication

open access: yes, 2021
In the present paper we construct a new intuitionistic fuzzy implication, giving intuitionistic fuzzy form to Goguen’s implication. Some of its basic properties are studied and illustrated with examples. Geometrical interpretations of the different forms

Ultra $LI$-ideals in lattice implication algebras [PDF]

open access: yes, 2002
summary:We define an ultra $LI$-ideal of a lattice implication algebra and give equivalent conditions for an $LI$-ideal to be ultra. We show that every subset of a lattice implication algebra which has the finite additive property can be extended to an ...
