| Title: | On the irreducibility of pseudovarieties of semigroups |
| Issue Date: | 2016 |
| Abstract: | We show that, for every pseudovariety of groups H, the pseudovariety (H) over bar, consisting of all finite semigroups all of whose subgroups lie in H, is irreducible for join and the Mal'cev and semidirect products. |
