Further results on strong edge-colourings in outerplanar graphs

Discrete Mathematics 2013-12-20 v1 Combinatorics

Abstract

An edge-colouring is {\em strong} if every colour class is an induced matching. In this work we give a formulae that determines either the optimal or the optimal plus one strong chromatic index of bipartite outerplanar graphs. Further, we give an improved upper bound for any outerplanar graph which is close to optimal. All our proofs yield efficient algorithms to construct such colourings.
