| Abstract: | Two semigroups S and T are weakly regular *-semigroups are verified if the subdirect product of S and T is a weakly regular*-semigroup.A construction of all subdirect products of weakly regular *-semigroups is obtained.By using this construction principle,E-unitary covers and pure covers of weakly regular *-semigroups are investigated. |

| Keywords: | weakly regular *-semigroup subdirect product E-unitary cover pure cover |
