1 Intersection graph characterization for p-BOX graphs
We recall that any p-BOX (1) -realization of a graph induces a natural ordering of its vertices by considering their respective representative elements.
We prove that for any graph G the existence of an ordering of its set of vertices that satisfies the four point condition for p-BOX (1) is necessary and sufficient to decide if G belongs to p-BOX (1).
