Tameness of joins involving the pseudovariety of local semilattices
In this paper we prove that, if V is a kappa-tame pseudovariety which satisfies the pseudoidentity xy^{\omega+1}z=xyz, then the pseudovariety join LSl v V is also kappa-tame. Here, LSl denotes the pseudovariety of local semilattices and kappa denotes the implicit signature consisting of the multipli...
