On the Co-PI Spectral Radius and the Co-PI Energy of Graphs

2017    Kaya, Ezgi; Maden, A. Dilek

The Co-PI eigenvalues of a connected graph G are the eigenvalues of its Co-PI matrix. In this study, Co-PI energy of a graph is defined as the sum of the absolute values of Co-PI eigenvalues of G. We also give some bounds for the Co-PI spectral radius and the Co-PI energy of graphs.
