Some Basic Principles on Posets, Hasse Diagrams and Lattices

WebLattice A poset (A;„) is a lattice iﬁ For all a;b 2 A lubfa;bg or glbfa;bg exist. y Lattice notation Observe that by deﬂnition elements lubB and glbB are always unique (if they exist). For B = fa;bg we denote: lubfa;bg = a[b and glbfa;bg = a\b. y Lattice union (meet) The element lubfa;bg = a \ b is called a lattice union (meet) of a and b. WebA lattice is a poset in which any two elements have a unique meet and a unique join. Lattices (in this form) show up in theoryCS in (briefly) the theory of submodularity (with the subset lattice) and clustering (the partition lattice), as well as in domain theory (which I don't understand too well) and static analysis. cy young pics

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.

Web• Abandon the requirement for a lattice! • What should we replace it with? • The minimal requirements seemed to be that you needed a poset in which chains had sups • Definition: A poset is chain-complete iff every chain has a sup. – There was some confusion about whether you should require directed sets to have sups and not just chains. 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.

WebA lattice is a poset ( , ) with two properties: • has an upper bound 1 and a lower bound 0; • for any two elements T, U∈ , there is a least upper bound and a greatest lower bound of a set { T, U}. In a lattice, we denote the least upper bound of { T, U} by T⋁ U and the greatest lower bound by T⋀ U.
