PENDANT NUMBER OF GRAPHS

Abstract

A decomposition of a graph $G$ is a collection of its edge disjoint sub-graphs such that their union is $G$. A path decomposition of a graph is a decomposition of it into paths. In this paper, we define the pendant number $\Pi_p$ as the minimum number of end vertices of paths in a path decomposition of $G$ and determine this parameter for certain fundamental graph classes.
