Bounds on the ABC spectral radius of a tree
Let G be a simple connected graph with vertex set {1,2,...,n} and di denote the degree of vertex i in G. The ABC matrix of G, recently introduced by Estrada, is the square matrix whose ijth entry is √((di+dj-2)/didi); if i and j are adjacent, and zero; otherwise. The entries in ABC matrix represent...
