Webcomplement. Remark x ∧y 0 iff y ≤x∗. That is, the complement x∗of x is the largest element whose meet with x is zero. Similarly, if x ∨y 1,theny≥x∗, that is, x∗is the smallest element whose join with x is one. Proof Recall that in any lattice, x ≤y is equivalent to x ∧y x, as well as to x ∨y y.Now, from x ∧y 0 we get x ∧y ∨y∗ 0 ∨y∗ y∗.
