Linear extensions of orderings

Czechoslovak Mathematical Journal Aims and scope Submit manuscript

Abstract

A construction is given which makes it possible to find all linear extensions of a given ordered set and, conversely, to find all orderings on a given set with a prescribed linear extension. Further, dense subsets of ordered sets are studied and a procedure is presented which extends a linear extension constructed on a dense subset to the whole set.
