It is shown that if 𝖵 is a local monoidal pseudovariety of semigroups, then 𝖪 ⓜ 𝖵, 𝖣 ⓜ 𝖵 and are local. Other operators of the form 𝖹 ⓜ(_) are considered. In the process, results about the interplay between operators 𝖹 ⓜ(_) and (_) * 𝖣k are obtained.

We show that if $\mathsf V$ is a semigroup pseudovariety containing the finite semilattices and contained in $\mathsf {DS}$, then it has a basis of pseudoidentities between finite products of regular

It is shown that ZG is local, that is, the semidirect product ZG ∗ D of ZG by definite semigroups is equal to LZG, the variety of semig groups where all local monoids are in ZG.

It is shown that it is decidable for a given regular language and a non-negative integer m, whether the language is definable by a formula in FO^2[<,suc] which has at most m quantifier alternations.

A Structural Approach to the Locality of Pseudovarieties of the Form LH (m) V
We show that if H is a Fitting pseudovariety of groups and V is a local pseudovariety of monoids, then LH ⓜ V is local if either V contains the six element Brandt monoid, or H is a non-trivial

Abstract. We use classical results on the lattice $\cal L (\cal B)$ of varieties of band (idempotent) semigroups to obtain information on the structure of the lattice Ps (DA) of subpseudovarieties

We offer a new proof of the theorem in the title. In fact, we prove that for any varietyH of groups of finite exponent, the varietyCR(H) of all completely regular monoids with subgroups fromH, is
