【Abstract】 The theory of graph spectrum is an important area in graph theory. In this paper,the author makes an estimate for the bounds of the spectral radius of graphs by the eigenvector corresponding to the largest eigenvalue,and obtains the upper bounds of the various forms of the spectral radius of graphs.更多还原
