Abstract:

Let be a graph with vertex set , and let be the degree of . The Zagreb matrix of is the square matrix of order whose - entry is equal to if the vertices and are adjacent, and zero otherwise. The Zagreb energy of is the sum of the absolute values of the eigenvalues of the Zagreb matrix. In this paper, we determine some classes of Zagreb hyperenergetic, Zagreb borderenergetic, and Zagreb equienergetic graphs.
