摘要
Let p be a prime number and n be a positive integer. The graph G(p)(n) is a graph with vertex set [n] = {1, 2,...,n}, in which there is an arc from u to v if and only if u not equal v and p inverted iota u + v. In this paper it is shown that G(p)(n) is a perfect graph. In addition, an explicit formula for the chromatic number of such graph is given.
