Did you know?
A partially ordered set (L, ≤) is a complete lattice if every subset A of L has both a greatest lower bound (the infimum, also called the meet) and a least upper bound (the supremum, also called the join) in (L, ≤). The meet is denoted by , and the join by . In the special case where A is the empty set, the meet of A will be the greatest element of L. Like… WebThe definitive generalization of Birkhoff’s the- orem to arbitrary distributive lattices was obtained in the sixties by Ann Priestley. Briefly, there is a nontrivial extension of the …

WebMar 24, 2024 · A partially ordered set (or ordered set or poset for short) (L,<=) is called a complete lattice if every subset M of L has a least upper bound (supremum, supM) and a greatest lower bound (infimum, infM) in (L,<=). Taking M=L shows that every complete lattice (L,<=) has a greatest element (maximum, maxL) and a least element (minimum, …
