Chronological orderings of interval graphs. (English) Zbl 0543.05059
An interval graph is a graph, which is the intersection graph of a set of intervals of the real line. The set of intervals is called an interval representation of the graph. This paper gives three methods for describing the differences of the order of the endpoints of the intervals along the line.
