This is about lattice theory. For other similarly named results, see Birkhoff's theorem (disambiguation). In mathematics, Birkhoff's representation theorem for distributive lattices states that the elements of any finite distributive lattice can be represented as finite sets, in such a way that the lattice operations correspond to … See more Many lattices can be defined in such a way that the elements of the lattice are represented by sets, the join operation of the lattice is represented by set union, and the meet operation of the lattice is represented by set … See more Consider the divisors of some composite number, such as (in the figure) 120, partially ordered by divisibility. Any two divisors of 120, such as 12 and 20, have a unique See more In any partial order, the lower sets form a lattice in which the lattice's partial ordering is given by set inclusion, the join operation corresponds to set … See more Birkhoff's theorem, as stated above, is a correspondence between individual partial orders and distributive lattices. However, it can also be extended to a correspondence between order-preserving functions of partial orders and bounded homomorphisms of … See more In a lattice, an element x is join-irreducible if x is not the join of a finite set of other elements. Equivalently, x is join-irreducible if it is neither the bottom element of the lattice (the join of … See more Birkhoff (1937) defined a ring of sets to be a family of sets that is closed under the operations of set unions and set intersections; later, motivated by applications in See more Infinite distributive lattices In an infinite distributive lattice, it may not be the case that the lower sets of the join-irreducible elements are in one-to-one correspondence … See more WebJan 1, 2012 · The aim of this paper is to investigate some properties of the lattice of all ideals of a BCK-algebra and the interrelation among them; e.g, we show that BCK (X), the lattice of all ideals of a ...

The Arithmetical Theory of Birkhoff Lattices SpringerLink

WebIn 1937, G. Birkhoff [6] proved that every element of a finite dimensional distributive lattice L has a “unique irredundant decomposition” as meet of meetirreducible elements (or as a join of join-irreducible elements). What does this mean? Let us denote by M(L) or simply M (resp. J(L) or J) the set of all meetirreducible (resp. join-irreducible) elements of a lattice … WebFor a bounded lattice A with bounds 0 and 1, Awill denote the lattice A-{0, 1} EXAMPLE : 1.1. 6 Consider the Boolean algebra B 2 , with 4 elements. ... slurry paint

Properties of Almost Distributive Lattices

WebJan 1, 2009 · The concept of Birkhoff center B(R) of an ADL with maximal elements was introduced by Swamy and Ramesh [8] and prove that B(R) is a relatively complemented Almost distributive lattice. The concept ... WebGarrett Birkhoff [1] has proved that a modular lattice in which every element is uniquely expressible as a reduced cross-cut of irreducibles is distributive. Furthermore, Moxgan Ward has shown that unicity of the irreducible decomposi-tions implies that the lattice is a Birkhoff lattice.2 These results suggest the WebGarrett Birkhoff.
