On the Edge-graceful Indices of P_2×C_n
Xia Li · Journal of Zhengzhou University · 2007
The condition is given out in which G=(V,E) is said to be k-edge-graceful graph.And by the especial property of regular graph,the necessary condition in which the graph P2×Cn is k-edge-graceful is discussed.A method to construct k-edge-graceful graph P2×Cn is given out by recursion and the problem of what sets of natural numbers are the edge-graceful indices of graph P2×Cn is completely resolved.
