Distances in Weighted Trees and Group Inverse of Laplacian Matrices [PDF]
SIAM Journal on Matrix Analysis and Applications, 1997 Formulas are given for group inverses of Laplacians of weighted trees. A relationship between entries of the group inverse and various distance functions on trees is highlighted. In particular, it is shown that the maximal and minimal entries on the diagonal of the group inverse correspond to certain pendant vertices of the tree and to a centroid of ...
