Description: |
The global of a pseudovariety of semigroups V is the smallest pseudovariety of semigroupoids which contains V, where members of V are viewed as one-vertex semigroupoids. When the global of the pseudovariety V is characterized by properties of the local semigroups of its semigroupoids, the pseudovariety V is said to be local. We study a family of Mal'cev operators of the form Z\malcev( ) showing that some of them preserve the locality of pseudovarieties. In the process, we deal with the localization operator L( ) and the semidirect product operator ( )*D establishing some interplay between them.
This is a joint work with A. Costa.
