Webelement is a meet of completely meet-irreducible elements, and that this generalizes the main result of Garrett Birkhoff [3](x) on subdirect unions in universal algebra. Komatu's necessary and sufficient conditions are derived for L to be isomorphic with the lattice of all ideals of another lattice A. A partially ordered set (L, ≤) is a complete lattice if every subset A of L has both a greatest lower bound (the infimum, also called the meet) and a least upper bound (the supremum, also called the join) in (L, ≤). The meet is denoted by , and the join by . In the special case where A is the empty set, the meet of A will be the greatest element of L. Like…
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 … WebFrom well known results in universal algebra [3, Cor. 14.10], the lattice of subvarieties of the variety of Birkhoff systems is dually isomorphic to the lattice of fully invari- ant …
