On the k-edge-graceful indices of S(3,n)
摘要
Abstract
Let k be a nonnegative integer,and G be a graph with p vertices and q edges.The graph G is called to be k-edge-graceful if there exists a bijection f:E--{ k,k+1,k+2,…,k + q-1 } such that the induced mapping f+.V→ Zp is a bijection too.We denote G is k-edge-graceful.In this paper,the defination is given out which G =(V,E) is called to be k-edge-graceful graph.And by the especial property of the graph,the necessary condition which the graph S(3,n) is k-edge-graceful is discussed.A method to construct k-edge-graceful graph S(3,n) is given out by recursion and the problem of what sets of natural numbers are the edge-graceful indices of graph S(3,n) is completely resolved when n is even.关键词
