In this paper, we show that among all the connected graphs with n vertices and k cut vertices, the maximal signless Laplacian spectral radius is attained uniquely at the graph G n,k , where G n,k is obtained from the complete graph K n-k by attaching paths of almost equal lengths to all vertices of
In [J. Molitierno, The spectral radius of submatrices of Laplacian matrices for trees and its comparison to the Fiedler vector, Linear Algebra Appl. 406 (2005) 253-271], we observed the effects on the spectral radius of submatrices of the Laplacian matrix L for a tree by deleting a row and column of
