Graph coloring is one of the chief topics in the graph research, the solution of the chromatic number of the graph is an NP-hard problem. Let G (V, E ) be a simple graph, k is a positive integer. f is a mapping from V (G )∪ E (G ) to {1, 2, …, k } such that 8704;uv ∈E (G ), then f (u )≠f (uv ), f (v )≠f (uv ), C (u )≠C (v ), f can be called the vertex-edge-adjacent vertex distinguishing total coloring of G (adjacent vertex distinguishing VE-total coloring of G ), χat ve (G )=min{k |k -VE-AVDTC} would be called the vertex-edge-adjacent vertex distinguishing total chromatic number of G (adjacent vertex distinguishing VE-total chromatic number of G ), where vertex-edge-adjacent vertex distinguishing total coloring of G C (u )={f (u )}∪{f (uv )|uv ∈E (G )}. In this paper, two kinds of crown graphs Cm ·Sn and Cm ·Pn are designed, the vertex-edge-adjacent vertex distinguishing total coloring of Cm ·Sn and Cm ·Pn are studied. According to the properties of two kinds of crown graphs Cm ·Sn and Cm ·Pn , by using colors one by one and in recursion, the vertex-edge-adjacent vertex distinguishing total chromatic numbers of two kinds of crown graphs Cm ·Sn and Cm ·Pn are obtained.
