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, …
