摘要
Let n >= 2 be an integer. The graph <(G(n))over bar> is obtained by letting all the elements of {0,.,.n - 1} to be the vertices and defining distinct vertices x and y to be adjacent if and only if gcd(x +y,n) not equal 1. In this paper, we give some bounds for the Castelnuovo-Mumford regularity of the edge ideals and their powers for<(G(n))over bar>.
