Abstract

We prove that if SS is an EE-solid locally inverse semigroup, and ρ\rho is an inverse semigroup congruence on SS such that the idempotent classes of ρ\rho are completely simple semigroups then SS is embeddable into a λ\lambda-semidirect product of a completely simple semigroup by S/ρS/\rho. Consequently, the EE-solid locally inverse semigroups turn out to be, up to isomorphism, the regular subsemigroups of λ\lambda-semidirect products of completely simple semigroups by inverse semigroups.
