Anr-acyclic edge coloring of a graphGis a proper edge coloring such that any cycleChas at leastcolors. The least number of colors needed for anr-acyclic edge coloring ofGis called ther-acyclic edge chromatic number or ther-acyclic chromatic index ofG, denoted by. In this paper, we study ther-acyclic edge chromatic number withand prove that. We also prove that whenris even,, which is asymptotically optimal. In addition, we investigate how ther-acyclic edge chromatic number performs as the girth increases. It is proved in this paper that for every graphGwith girth at least,holds. Our approach is based on the entropy compression method.
