Distance spectral radius of trees with fixed maximum degree.

On the sum of powers of Laplacian eigenvalues of bipartite graphs
For a bipartite graph and a non-zero real , we give bounds for the sum of the th powers of the Laplacian eigenvalues of using the sum of the squares of degrees, from which lower and upper bounds for the incidence energy, and lower bounds for the Kirchhoff index and the Laplacian Estrada index are deduced.
