The aim of this paper is to investigate the lattices of group fuzzy congruences and normal fuzzy subsemigroups on E-inversive semigroups. We prove that group fuzzy congruences and normal fuzzy subsemigroups determined each other in E-inversive semigroups. Moreover, we show that the set of group t-fuzzy congruences and the set of normal subsemigroups with tip t in a given E-inversive semigroup form two mutually isomorphic modular lattices for every t ∈ [0,1].
本文旨在研究E-逆半群上的群模糊同余格和正规模糊子半群。我们证明了在E-逆半群中,群模糊同余和正规模糊子半群相互确定。此外,我们表明,对于给定的E-逆半群,对于每个t∈[0,1],群t-模糊同余集和具有尖端t的正规子半群集形成两个相互同构的模格。
