Generalizations of (∈,∈∨q)-fuzzy subalgebras in BCK/BCI-algebras
Computers and Mathematics With Applications, 2009 More general form of the notion of quasi-coincidence of a fuzzy point with a fuzzy set is considered, and generalizations of results in the papers [Y. B. Jun, On (α,β)-fuzzy subalgebras of BCK/BCI-algebras, Bull. Korean Math. Soc.

On (Alpha, Beta) Fuzzy Subalgebras of BCH-Algebras
2008 Fifth International Conference on Fuzzy Systems and Knowledge Discovery, 2008By two relations belonging to and quasi-coincidence between fuzzy points and fuzzy sets, we define the concept of (alpha, beta)-fuzzy subalgebras where a, beta are any two of {isin.g, isin Vq, isin Lambdaq} with alpha neisin Lambdaq. We state and prove some theorems in (alpha,beta)-fuzzy subalgebras of BCH-algebras.

On the lattice of fuzzy weak subalgebras of a fuzzy partial algebra
2002 Annual Meeting of the North American Fuzzy Information Processing Society Proceedings. NAFIPS-FLINT 2002 (Cat. No. 02TH8622), 2003Fuzzy partial algebras can be understood as incomplete algebraic structures whose elements are uncertain or imprecise, and thus fuzzy weak subalgebras of a fuzzy algebra correspond to structural approximations of the knowledge represented by the fuzzy algebra. In this paper we characterize those lattices that are isomorphic to the lattice of fuzzy weak

Length and mean fuzzy UP-subalgebras of UP-algebras
2022Summary: The aim of this paper is to introduce the notions of the length and the mean of a hyper structure in UP-algebras. The notions of length fuzzy UP-subalgebras and mean fuzzy UP-subalgebras of UP-algebras are introduced, and related properties are investigated.

Extended Fuzzy $BCK$-subalgebras
2016This paper extends the notion of fuzzy $BCK$-subalgebras to fuzzy hyper $BCK$-subalgebras and defines an extended fuzzy $BCK$-subalgebras. This study considers a type of fuzzy hyper $BCK$-ideals in this hyperstructure and describes the relationship between hyper $BCK$-ideals and fuzzy hyper $BCK$-ideals. In fact, it tries to introduce

L-Fuzzy Subalgebras and L-Fuzzy Filters of R0-Algebras
2011R0-algebras are the logic algebras associated to the formal deductive system L* for fuzzy propositional calculus. In this paper, the concepts of L-fuzzy subalgebras and L-fuzzy filters of R0-algebras are introduced. Properties of L-fuzzy subalgebras and L-fuzzy filters are investigated. characterizations of L-fuzzy subalgebras and L-fuzzy filters of R0-
