Abstract

In this paper we prove: Theorem. Let V \mathbf {V} and W \mathbf {W} be nontrivial lattice varieties. If L V W L \in \mathbf {V} \circ \mathbf {W} , then there is a subdirectly irreducible S V W S \in \mathbf {V} \circ \mathbf {W} containing L L as a sublattice. Moreover, if L L is finite, S S can also be chosen to be finite.
