On the Sheffer stroke operation in fuzzy logic

open access: yesFuzzy Sets and Systems, 2022
From the beginnings of fuzzy logic, the Sheffer stroke operation has been overlooked and the efforts of the researchers have been devoted to other logical connectives. In this paper, the Sheffer stroke operation is introduced in fuzzy logic generalizing the classical operation when the truth values are restricted to {0, 1}(2).

Fuzzy Ideals of Sheffer Stroke Hilbert Algebras

Proceedings of the National Academy of Sciences India Section A - Physical Sciences, 2022
In this study, fuzzy subalgebras and ideals with t-conorms on Sheffer stroke Hilbert algebras are discussed. We state and prove relationships between the level-set of a fuzzy subalgebra with a t-conorm T (briefly, T-fuzzy subalgebra) and a subalgebra of a Sheffer stroke Hilbert algebra.

On Fuzzy Sheffer Stroke Be-Algebras

New Mathematics and Natural Computation, 2023
In this study, fuzzy Sheffer stroke BE-algebras are studied. Then a fuzzy SBE-subalgebra, a fuzzy SBE-filter, the cartesian product of fuzzy subsets and fuzzy points on a Sheffer stroke BE-algebra (briefly, SBE-algebra) are defined and it is shown that the family of all fuzzy points in a SBE-algebra is a weak SBE-algebra which is usually not a SBE ...

Replacement—A Sheffer Stroke for Belief Change

Journal of Philosophical Logic, 2009
In the AGM logic of belief change, the two basic change operations are contraction and revision, alongside the univocal, and hence unproblematic, classical operation of expansion. In the paper under review, the author introduces a more complex operation of `replacement', in which a sentence \(x\) is removed from a belief set while at the same time ...

Fuzzy filters of Sheffer stroke Hilbert algebras

Journal of Intelligent and Fuzzy Systems, 2021
The aim of this study is to introduce fuzzy filters of Sheffer stroke Hilbert algebra. After defining fuzzy filters of Sheffer stroke Hilbert algebra, it is shown that a quotient structure of this algebra is described by its fuzzy filter. In addition to this, the level filter of a Sheffer stroke Hilbert algebra is determined by its fuzzy filter.

Sheffer stroke R_{0}-algebras

2023
The main objective of this study is to introduce Sheffer stroke R0?algebra (for short, SR0? algebra). Then it is stated that the axiom system of a Sheffer stroke R0?algebra is independent. It is indicated that every Sheffer stroke R0?algebra is R0?algebra but specific conditions are necessarily for the inverse.
