Abstract
A Pâ-decomposition of a graph G is a set of edge-disjoint copies of Pâ in G that cover the edge set of G, where Pâ is the path with â edges. Kouider and Lonc [M. Kouider, Z. Lonc, Path decompositions and perfect path double covers, Australas. J. Combin. 19 (1999) 261-274] conjectured that any 2â-regular graph G admits a Pâ-decomposition D where every vertex of G is the end-vertex of exactly two paths of D. In this paper we verify Kouider and Lonc's Conjecture for paths of length 4.
