Fuzzy Ideals of Sheffer Stroke Hilbert Algebras
Proceedings of the National Academy of Sciences, India Section A: Physical Sciences, 2022In 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, 2023In 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 ...

(Anti) fuzzy ideals of Sheffer stroke BCK-algebras
2023Summary: The aim of this study is to introduce (anti) fuzzy ideals of a Sheffer stroke BCK-algebra. After describing an anti fuzzy subalgebra and an anti fuzzy (sub-implicative) ideal of a Sheffer stroke BCK-algebra, the relationships of these structures are demonstrated.

On ideals of Sheffer stroke UP-algebras
Journal of Discrete Mathematical Sciences & Cryptography, 2023The goal of the study is to introduce SUP-ideals on Sheffer Stroke UP-algebras (briefly, SUP-algebra) and its properties. We define SUP-ideals of SUP-algebras and then prove some properties. By describing a congruence relation on a SUP-algebra by the SUP-ideal, it is shown that the quotient set defined by the congruence relation is a SUP-algebra ...

Sheffer Stroke Fuzzy Implications
2017A new family of fuzzy implications, motivated by classic Sheffer stroke operator, is introduced. Sheffer stroke, which is a negation of a conjunction and is called NAND as well, is one of the two operators that can be used by itself, without any other logical operators, to constitute a logical formal system.

Fuzzy filters of Sheffer stroke Hilbert algebras
Journal of Intelligent & Fuzzy Systems, 2021The 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.

Hesitant Fuzzy Structures on Sheffer Stroke BCK-Algebras
New Mathematics and Natural Computation, 2022The main objective of the study is to introduce a hesitant fuzzy structures on Sheffer stroke BCK-algebras related to their subsets (subalgebras as possible as). Then it is proved that every hesitant fuzzy ideal of a Sheffer stroke BCK-algebra related to the subset is the hesitant fuzzy subalgebra.

Replacement—A Sheffer Stroke for Belief Change
Journal of Philosophical Logic, 2009In 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 ...
