摘要: This article proves the following result: Let G and G′ be graphs of orders n n′, respectively. G* obtained from by adding to each vertex a set n′ degree 1 neighbors. If has game coloring number m acyclic chromatic k, then Cartesian product GsG′ at most k(k + m - 1). As consequence, two forests 10, planar 105. © 2008 Wiley Periodicals, Inc.
