Commutators in Completely Simple Semigroups
Abstract
We 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 H-classes are nilpotent (solvable) groups.
