Birkhoff compact lattice greatest element

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 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.
