Commutators in completely simple semigroups
Semigroup ForumWe obtain a characterization of the binary commutator on completely simple semigroups, using their Rees matrix representation. Consequently, we prove that a regular semigroup is nilpotent (solvable) if and only if it is simple, and all its $\mathcal{H}$-classes are nilpotent (solvable) groups.

The Lattice of Equational Classes of Commutative Semigroups [PDF]
, 1970 Commutative semigroup equations are described, and rules of inference for them are given. Then a skeleton sublattice of the lattice of equational classes of commutative semigroups is described, and a partial description is given of the way in which the ...

Locally commutative power semigroups and counting factors of words
, 1993 This paper deals with the calculation of power pseudovarieties which consist of locally commutative semigroups. It provides the solution of some equations and inequalities involving the power operator as well as some upper bounds for specific power ...

LC-commutative permutable semigroups
Semigroup Forum, 1996 A semigroup \(S\) is called permutable if \(\rho \circ \sigma = \sigma \circ \rho\) for all congruences \(\rho\), \(\sigma\) on \(S\). A semigroup is called \(L\)-commutative if for every \(a, b \in S\) there is an element \(x \in S^1\) such that \(ab = xba\).

On Commutative Monoid Congruences of Semigroups
, 2015 A subset A of a semigroup S is called a medial subset of S if xaby is in A if and only if xbay is in A for every elements x, y, a, b of S. In the paper we show how we can construct the commutative monoid congruences of a semigroup S by the help of medial subsets of S.
