چکیده
|
In this paper, for a connected graph g and a real α /= 0, we define a new graph invariant σ_α (g)-as the sum of the αth powers of the normalized signless laplacian eigenvalues of g. note that σ1/2 (g) is equal to randić (normalized) incidence energy which have been recently studied in the liter- ature [5,15]. we present some bounds on σ_α (g) (α /= 0, 1) and also consider the special case α = 1/2.
