NettetAbstract. The best known connection between partial orders and linear orders is the Szpilrajn theorem: Any partial order on a set can be extended to a linear order on the same set. From this, it follows that any partial order is the intersection of its linear extensions; equivalently, every ordered set can be represented as some subset of a ...
