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

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-

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.

Formulas on the lattice of fuzzy subalgebras in universal algebra
Fuzzy Sets and Systems, 2007The transfer principle is studied. The notions of transferable form and strict-transferable form of open formulas are introduced and it is proved that the transfer principle holds both for universal sentences whose matrices are of the former type and existential sentences whose matrices are of the latter type, giving the equivalence for every abstract ...

$$ ( \in , \in \vee q) $$ ( ∈ , ∈ ∨ q ) -Fuzzy Lie Subalgebra and Ideals
International Journal of Fuzzy Systems, 2015There is an error in the proof of part $$ ({\text{iii}}) \Rightarrow (3) $$ of Theorem 4.2 in Davvaz and Mozafar (Int J Fuzzy Syst 11(2):123–129, 2009).

Fuzzy Pseudo Subalgebras and Ideals of Pseudo D-Algebras
Mathematica Slovaca, 2015Abstract The fuzzification of pseudo subalgebras/ideals in d-algebras and pseudo BCK-ideals is discussed. Several properties are investigated. Relations between fuzzy pseudo BCK-ideals and fuzzy pseudo d-ideals are established. Conditions for a fuzzy set to be a fuzzy pseudo BCK-ideal are considered.

Lattice of fuzzy subalgebras and closure systems in Ix
Fuzzy Sets and Systems, 1991For a given universal algebra \(A=[X,F]\) with a specified set F of finitary operations on the set X, each operation is extended to a finitary operation on the lattice \(I^ X\) of fuzzy subsets of X over the unit interval of real numbers \(I=[0,1]\).

Anti-Fuzzy Subalgebras of Fuzzy Points in Sheffer Stroke Hilbert Algebras
New Mathematics and Natural ComputationThis paper introduces novel concepts concerning anti-fuzzy subalgebras within the framework of Sheffer stroke Hilbert algebras. Using the notion of anti-fuzzy points and their relationships specifically, besideness to and nonquasi-coincidence with fuzzy sets, new types of anti-fuzzy subalgebras are defined and their fundamental properties are examined.
