Abstract: Let F(x) = n=1s1,s2, ...,sk(n)xn be the generating function for the number τs1,s2, ...,sk(n) of spanning trees in the circulant graph Cn(s1, s2, ..., sk). We show that F(x) is a rational function with integer coefficients satisfying the property F(x) = F(1/x). A similar result is also true for the circulant graphs C2n(s1, s2, ..., sk, n) of odd valency. We illustrate the obtained results by a series of examples.
