Abstract
In this paper, we introduce a concept of L-E-fuzzy skew lattices as a particular fuzzified version of skew lattices relative to lattice-valued algebraic structures, with fuzzy equality and fuzzy identities. In particular, L-E-fuzzy version of Green’s relations are also introduced as fuzzified forms of their classical ones in semigroup theory, and several equivalent forms of the fuzzy relations are obtained. Finally, we mainly prove that: (1) The L-E-fuzzy Green’s relations of L-E-fuzzy skew lattices are fuzzy compatible equalities on them; (2) The cut sets of L-E-fuzzy skew lattices are classical subalgebras in underlying algebras and, finally, we prove two important decomposition theorems concerning quotient algebras of cut sets over the fuzzy Green’s relations.
