Letbe a simple graph andT(G) be the set of vertices and edges ofG. LetCbe ak-color set. A (proper) totalk-coloringfofGis a functionsuch that no adjacent or incident elements ofT(G) receive the same color. For any, denote. The totalk-coloringfofGis called the adjacent vertex-distinguishing iffor any edge. And the smallest number of colors is called the adjacent vertex-distinguishing total chromatic numberofG. In this paper, we prove thatfor all connected graphs with maximum degree three. This is a step towards a conjecture on the adjacent vertex-distinguishing total coloring.
