WebA partially ordered set L is called a lattice when lub(fa;bg) and glb(fa;bg) exist for every two elements, a;b 2L. If L is a lattice, then glb(X) and lub(X) exist for every finite subset X µL. However this conclusion does not hold when X is infinite. A lattice L, is a complete lattice, when it contains the lub(X) and glb(X) for every X µL.
