Local finiteness for Green relations in (I-)semigroup varieties
Pedro V. Silva, Filipa Soares
In this work, the lattice of varieties of semigroups and the lattice of varieties of I-semigroups (a common setting for both the variety of completely regular semigroups and the va…

Howson's property for semidirect products of semilattices by groups
Pedro V. Silva, Filipa Soares
An inverse semigroup is a Howson inverse semigroup if the intersection of finitely generated inverse subsemigroups of is finitely generated. Given a locally finite action $…
