“…Some version of Meyer's Theorem is true for bilinear operators: If X, Y , and Z are vector lattices and B : X × Y → Z is an order bounded disjointness preserving bilinear operator then B possesses the positive part B + , the negative part B − , and the modulus |B|, which are lattice bimorphisms; moreover, B + (x, y) = B(x, y) + and B − (x, y) = B(x, y) − for all x ∈ X + and y ∈ Y + , and |B|(|x|, |y|) = |B(x, y)| for all x ∈ X and y ∈ Y ; see [11,Theorem 5] and [21,Theorem 3.4]. In particular, B is regular.…”
