On ω-Identities over finite aperiodic semigroups with commuting idempotents
| Summary: | The word problems for ω-terms over the pseudovariety of aperiodic semigroups with commuting idempotents and over the pseudovariety generated by finite aperiodic inverse semigroups are studied. The two problems have different solutions, thus showing that the two pseudovarieties are distinct, a result proven by Higgins and Margolis. |
