چکیده
|
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.
