Labeled Packing of Non Star Tree into its Fifth Power and Sixth Power

preprint2013arXivOpen access

Abstract

In this paper we prove that we can find a labeled packing of a non star tree TT into T6T^6 with mT+⌈n−mT5⌉m_T+\lceil\frac{n-m_T}{5}\rceil labels, where nn is the number of vertices of TT and mTm_T is the maximum number of leaves that can be removed from TT in such a way that the obtained graph is a non star tree. Also, we prove that we can find a labeled packing of a non star tree TT into T5T^5 with mT+1m_T+1 labels and a labeled packing of a path PnP_n, n≥4n\geq 4, into Pn4P_n^4 with ⌈n4⌉\lceil \frac{n}{4}\rceil labels.
