Birkhoff compact lattice greatest element
WebTHEOREM 4: Any finite- lattice can be represented by one or more graphs in space, bvi not every graph represents a lattice. In constructing representations, we shall need the notion of "covering". An element a of a lattice L is said to "cover" an elemen 6 oft L if and only if a 3 b (i.e. a^ b = a), a =# b, and a~>ob implies eithe c =r a or c = b. WebAs usual, 1~ 2 denote the chains of one and two elements, respectively and in general n denotes the chain of n elements. If P is a partially ordered set, then we use [x,y] to denote the set {z E P : x < z < y}. If L is a bounded distributive lattice, by …
