Let G be a graph of order n and let Q(G, x) = det(xI- Q(C)) = Sigma(n)(i)=(0)(-1)(i) zeta(i)x(n-1) be the characteristic polynomial of the signless Laplacian matrix of G. We show that the Lollipop graph, has the maximal Q-coefficients, among all unicyclic graphs of order n except Cn. Moreover, we determine graphs with minimal Q-coefficients, among all unicyclic graphs of order n. |
