Let G be a planar graph and let g(G) and Γ(G) be its girth and maximum degree, respectively. We show that G has an edge-partition into a forest and a subgraph H so that (i) -cycles (though it may contain 3-cycles). These results are applied to find the following upper bounds for the game coloring n

## Abstract A Ξ»βcoloring of a graph G is an assignment of Ξ» or fewer colors to the points of G so that no two adjacent points have the same color. Let Ξ© (n,e) be the collection of all connected nβpoint and eβedge graphs and let Ξ©p(n,e) be the planar graphs of Ξ©(n, e). This paper characterizes the g
In this article we study the monochromatic cycle partition problem for non-complete graphs. We consider graphs with a given independence number (G) = . Generalizing a classical conjecture of Erd" os, GyΓ‘rfΓ‘s and Pyber, we conjecture that if we r-color the edges of a graph G with (G) = , then the ver
Wallis, W.D. and G.-H. Zhang, On the partition and coloring of a graph by cliques, Discrete Mathematics 120 (1993) 191-203. We first introduce the concept of the k-chromatic index of a graph, and then discuss some of its properties. A characterization of the clique partition number of the graph G V
## Abstract The distance coloring number __X__~__d__~(__G__) of a graph __G__ is the minimum number __n__ such that every vertex of __G__ can be assigned a natural number __m__ β€ __n__ and no two vertices at distance __i__ are both assigned __i__. It is proved that for any natural number __n__ ther
This paper discusses a variation of the game chromatic number of a graph: the game coloring number. This parameter provides an upper bound for the game chromatic number of a graph. We show that the game coloring number of a planar graph is at most 19. This implies that the game chromatic number of a
