| Abstract: | The srectral of weighted graphs are often used to solve the problems in the design of networks and electronic circuits.In the paper we study the relationships between the adjacent spectral radius of weighted trees which have fixed positive weight set and the independence number,matching number,covering number,then determine the weighted tree with the largest adjacent spectral radius. |
