Abstract
Let Σn i=0(-1)ilixn-i and PΣ i=0(-1)iqixn-i be the characteristic polynomials of the Laplacian matrix and signless Laplacian matrix of an n-vertex graph, respectively. Let αi = Iqi - lil, 0 i n. In this paper, we find formulas for some of αi’s. In particular, we compute αi’s for some fullerene graphs.
