%0 Journal Article %T Howson's property for semidirect products of semilattices by groups %A Pedro V. Silva %A Filipa Soares %J Mathematics %D 2014 %I arXiv %X An inverse semigroup $S$ is a Howson inverse semigroup if the intersection of finitely generated inverse subsemigroups of $S$ is finitely generated. Given a locally finite action $\theta$ of a group $G$ on a semilattice $E$, it is proved that $E \ast_{\theta} G$ is a Howson inverse semigroup if and only if $G$ is a Howson group. It is also shown that this equivalence fails for arbitrary actions. %U http://arxiv.org/abs/1412.3048v1
