Let V be a vector space over a field and let T(V) denote the semigroup of all linear transformations from V into V. For a fixed subspace W of V, let F(V,W) be the subsemigroup of T(V ) formed by all linear transformations α from V into W such that V α ⊆ W α. We prove that any regular semigroup S can be embedded in F(V,W) with dim(V) = |S1| and dim(W) = |S|, and determine all maximal subsemigroups of F(V,W) in the case where W is a finite-dimensional subspace of V over a finite field.
