modular ordered set; relatively complemented ordered set; atom
The authors investigate conditions for the existence of relative complements in ordered sets. For relatively complemented ordered sets with \(0\) they show that each element \(b\neq 0\) is the least one of the set of all upper bounds of all atoms contained in \(b\).
