Lattice of partially ordered fuzzy subalgebras

Fuzzy Sets and Systems, 1996
A \(P\)-fuzzy subalgebra of an algebra \(A\) is a mapping \(M: A\to P\) (where \(P\) is a partially ordered set) such that for every \(p\in P\) the level set \(M_p= \{x\mid x\in A, M(x)\geq p\}\) is a subalgebra of \(A\). In case \(P\) is a lattice \(L\), \(M\) is called an \(L\)-fuzzy subalgebra of \(A\).

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 ...

Representation of fuzzy subalgebras by crisp subalgebras

Fuzzy Sets and Systems, 2003
For any nonempty set \(X\), let \(X_L\) denote the set of all fuzzy points of \(X\). A subset \(Z\) of \(X_L\) is called closed if for any \(x\in X\) and any \(M\subseteq L\), the fuzzy point \(F_x^{\sup M}\in Z\Leftrightarrow F^a_x\in Z\) for all \(a\in M\).

Lattice of fuzzy subalgebras in universal algebra

Algebra Universalis, 2002
This paper is devoted to the so-called fuzzy subalgebras of universal algebras. A fuzzy subalgebra of an algebra \(A\) is a fuzzy subset of \(A\) which is closed (in a natural way generalizing the non-fuzzy case) with respect to the operations of \(A\). The authors show a bijective correspondence between fuzzy subalgebras of \(A\) and so-called weights

Relations and homomorphisms of fuzzy hyper BE –subalgebras

Journal of Intelligent & Fuzzy Systems, 2016
This paper introduces the notion of (locally) fuzzy homomorphism in fuzzy hyper BE –subalgebra and makes a connection between fuzzy BE –algebras and hyper BE –algebras via this notion.

On fuzzy (hyper) EQ-subalgebras

2018 6th Iranian Joint Congress on Fuzzy and Intelligent Systems (CFIS), 2018
This paper introduces the notion of fuzzy hyper EQ-subalgebras as generalization of the notation of fuzzy EQ-subalgebras and constructs extendable fuzzy EQ-subalgebras via these concepts. Moreover, we investigated some properties in fuzzy EQ-subalgebras, fuzzy hyper EQ-subalgebras by their α-level sets and connect them via positive fundamental relation
