Some Relations Among the Largest Eigenvalues of Product Matrix and Graph Matrices
Abstract
We define product matrix as , where is an adjacency matrix and is a diagonal matrix of vertex degrees of a graph . In this paper, some relations among the spectral radius of product matrix and the largest eigenvalues of graph matrices are obtained. We also give numerical results for them.
