Orders in completely regular semigroups
Mathematika, 2001A classic theorem of semigroup theory is that a semigroup \(S\) has a group of quotients if and only if it is reversible and cancellative. From the perspective of the group, it contains \(S\) as an ``order''. Generalizing from both this situation and from ring theory, a semigroup \(S\) is an order in another semigroup \(Q\) if every element in \(Q ...

Fuzzy congruences on a regular semigroup
Fuzzy Sets and Systems, 2001The 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)].
