be a strong semilattice of semigroups such that
is finite and each
be a family of disjoint semigroups. In this article some finiteness conditions which are periodicity, local finiteness and locally finite presentability are considered for
. It is proven that a strong semilattice of semigroups
is periodic, locally finite, locally finitely presented and residually finite, respectively if and only if
is finite and each semigroup
is periodic, locally finite, locally finitely presented and residually finite, respectively.
