摘要
The unitary Cayley graph Xn has the vertex set Z(n) = {0, 1, 2, .., n-1} and vertices a and b are adjacent, if and only if gcd(a-b, n) = 1. In this paper, we present some properties of the clique, independence and distance polynomials of the unitary Cayley graphs and generalize some of the results from [W. Klotz, T. Sander, Some properties of unitary Cayley graphs, Electr. J. Comb. 14 (2007), #R45]. In addition, using some properties of Laplacian polynomial we determine the number of minimal spanning trees of any unitary Cayley graph.
