Abstract:

The fractional arboricity of a graph G, denoted by gamma(f)(G), is defined as gamma(f)(G) = max(H subset of G, nu(H)>1), e(H)/nu(H)-1,. The famous Nash-Williams' Theorem states that a graph G can be partitioned into at most k forests if and only if gamma(f)(G) <= k. A graph is d-bounded if it has maximum degree at most d. The Nine Dragon Tree (NDT) Conjecture [posed by Montassier, Ossona de Mendez, Raspaud, and Zhu, at [11]] asserts that if gamma(f)(G) <= k + d/k+d+1, then G decomposes into k + 1 forests with one being d-bounded. In this paper, it is proven that the Nine Dragon Tree Conjecture is true for all the cases in which d = 1. (C) 2018 Elsevier Inc. All rights reserved.
