Fuzzy congruences on a regular semigroup
The paper examines lattices of fuzzy equivalence relations [cf. \textit{L. A. Zadeh}, Inf. Sci. 3, 177-200 (1971; Zbl 0218.02058)] on a regular semigroup. In particular properties of the lattice of fuzzy congruences are considered. This is a continuation of a paper by \textit{M. A. Samhan} [Inf. Sci. 74, No. 1-2, 165-175 (1993; Zbl 0785.20034)].
