E*-dense E-semigroups

We investigate E^*-dense semi-groups as analogues of E-densesemigroupsfor semigroups with zero. We give a characterisation theorem forE^*-dense semigroups whose idempotents form a *-rectangularband. The construction methods of generalised Rees matrix semigroupsare employed to provide examples and illustrations. Our results areanalogous to those of Weipoltshammer for E-dense semigroups.
