Title
The locality of some subpseudovarieties of DG

Abstract
The global of a pseudovariety of monoids is the pseudovariety of categories generated by its elements when they are viewed as the monoids of edges in one-vertex categories. The global of a pseudovariety of monoids is useful to compute various operators involving the pseudovariety. When the global of the pseudovariety is characterized by properties of the local submonoids of its categories, the pseudovariety is said to be local. Using syntactic arguments, we prove that some subpseudovarieties of DG, the pseudovariety of all finite monoids whose D-classes are groups, are local.
