Chromatic Polynomial of Circulant Graph with Two Parameters












2












$begingroup$


It is easy to get the Chromatic-Polynomial of a Circulant-Graph of size $n$ with one parameter $P[C_{n}(i),x]$. Is there a way to get an explicit formula for the chromatic polynomial of a circulant graph with two parameters? I am particularly interested in the asymptotic behavior of the expression



$$frac{P[C_{n}(i,j),n]}{n^n} - frac{P[C_{n}(i),n]*P[C_{n}(j),n]}{n^{2n}}$$



as $ nrightarrowinfty$.
