摘要An acyclic vertex (or edge) coloring of a graph G is a proper vertex (or edge) coloring such that no bichromatic cycles are produced. The acyclic chromatic number (or index) of G is de?ned as the smallest integer k such that G has an acyclic vertex (or edge) coloring using k colors. In this talk we give a survey on the research progress for the acyclic vertex coloring and the acyclic edge coloring of graphs. In particular, we study the acyclic chromatic number (or index) of some special graphs such as 4-regular graphs, planar graphs, 1-planar graphs, K4-minor free graphs, etc.
