For a graph G the degree sum adjacency matrix DSA(G) is defined as a matrix, in which every element is sum of the degrees of the vertices if and only if the corresponding vertices are adjacent, otherwise it is zero. In this paper we obtain the bounds for the spectral radius and partial sum of the eigenvalues of the DSA matrix. We also find the bounds for the DSA energy of a graph in terms of its Zagreb indices. |
