On inverse semigroups the closure of whose set of idempotents is a clifford semigroup
The semigroups mentioned in the title \{they form the first uninvestigated class in the \textit{M. Petrich} and \textit{N. R. Reilly} diagram [Trans. Am. Math. Soc. 270, 309-325 (1982; Zbl 0484.20026)]\} are exactly the inverse subsemigroups of semidirect products of a Clifford semigroup and a group. Under an additional condition \textit{D. B. McAlister}'s \(P\)-theorem [ibid. 196, 351-370 (1974; Zbl 0297.20072)] can be generalized, too.
