## Abstract A proper coloring of the edges of a graph __G__ is called __acyclic__ if there is no 2โcolored cycle in __G__. The __acyclic edge chromatic number__ of __G__, denoted by __aโฒ__(__G__), is the least number of colors in an acyclic edge coloring of __G__. For certain graphs __G__, __aโฒ__(_

โฆ Synopsis
A k-forest is a forest in which the maximum degree is k. The k-arboricity denoted Ak(G) is the minimum number of k-forests whose union is the graph G. We show that if G is an m-degenerate graph of maximum degree A, then Ak(G) 5 [(A + (k -1) m -1)/k], k 2 2, and derive several consequences of this inequality.

## Abstract An __acyclic__ edge coloring of a graph is a proper edge coloring such that there are no bichromatic cycles. The __acyclic chromatic index__ of a graph is the minimum number __k__ such that there is an acyclic edge coloring using __k__ colors and is denoted by __a__โฒ(__G__). A graph is
An __acyclic edgeโcoloring__ of a graph is a proper edgeโcoloring such that the subgraph induced by the edges of any two colors is acyclic. The __acyclic chromatic index__ of a graph __G__ is the smallest number of colors in an acyclic edgeโcoloring of __G__. We prove that the acyclic chromatic inde

Let x'(G), called the strong coloring number of G, denote the minimum number of colors for which there is a proper edge coloring of a graph G in which no two of its vertices is incident to edges colored with the same set of colors. It is shown that Z'~(G) ~< Fcn], ยฝ < c ~ 1, whenever A(G) is appropr
