How to determine if given lattice is distributive or not?

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.

D6 / poset is a lattice or not say yes or no

WebAn element m in a poset S is called a lower bound of a subset A of S if m precedes every element of A, i.e. if, for every y in A, we have m <=y . If a lower bound of A succeeds every other lower bound of A, then it is called the infimum of A and is denoted by Inf (A) Web1. Preliminaries. We shall denote the ordering relation in a poset by ^. Let A = {ai\ i£:l\ be a subset of a poset P. Then the least upper bound (l.u.b.) and the greatest lower bound (g.l.b.) of A are also called the lattice-sum and the lattice-product of the a,-; they are denoted by ^,e/ a. and IJier o¿ respectively.
