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 … WebDec 30, 2024 · It is immediate that every finite lattice is complete and atomic, i.e., every element is above some atom. So the following result yields that a finite uniquely …

WebIn a complete lattice, is every join of arbitrary elements equal to a join of a finite number of elements? 1 Meet of two compact elements need not to be compact. 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
