Title
On an interpolation property of outerplanar graphs
Abstract
Let D be an acyclic orientation of a graph G. An arc of D is said to be dependent if its reversal creates a directed cycle. Let d(D) denote the number of dependent arcs in D. Define dmin(G) (dmax(G)) to be the minimum (maximum) number of d(D) over all acyclic orientations D of G. We determine dmin(G) for an outerplanar graph G and prove that G has an acyclic orientation with exactly k dependent arcs if dmin(G) ≤ k ≤ dmax(G).
