If the lattice point p x y z
WebIt remains to be proven that (P,⊑) is a complete lattice. Let Y be any subset of P. We must prove that Y has a least upper bound. For this purpose,consider theinterval lattice ([⊔Y,⊤],⊑) which, by Lemma1, is complete. We want to prove that f′: [⊔Y,⊤] → [⊔Y,⊤] defined by f′(x) = f(x), for all x ∈ [⊔Y,⊤], is in fact a ...
