Let E and F be uniformly complete vector lattices with disjoint complete systems ( u i ) i ∈ I and ( v i ) i ∈ I of projection elements of E and F respectively. In this paper we prove that if T is a lattice homomorphism from E into F with T ( λu i ) = λv i for each λ ∈ ℝ and i ∈ I then T is linear. This generalizes the main results of [4] and [5].
