In this study, we have obtained bounds for extreme singular values of a complex matrix A of order n × n . In addition, we have found a bounds for the extreme singular values of Hilbert matrix, its Hadamard square root, Cauchy-Toeplitz matrix, Cauchy

The spread of the singless Laplacian of a simple graph G is defined as SQ(G) = mu(1)(G) - mu(n)(G), where mu(1)(G) and mu(n)(G) are the maximum and minimum eigenvalues of the signless Laplacian matrix of G, respectively. In

The main purpose of this paper is to define and investigate the Kirchhoff matrix, a new Kirchhoff index, the Kirchhoff energy and the Kirchhoff Estrada index of a graph. In addition, we establish upper and lower bounds for these new indexes and energ
