- W2896820451 abstract "Let $T$ be a tree with vertex set ${1, ldots, n}$ such that each edge is assigned a nonzero weight. The squared distance matrix of $T,$ denoted by $Delta,$ is the $n times n$ matrix with $(i,j)$-element $d(i,j)^2,$ where $d(i,j)$ is the sum of the weights of the edges on the $(ij)$-path. We obtain a formula for the determinant of $Delta.$ A formula for $Delta^{-1}$ is also obtained, under certain conditions. The results generalize known formulas for the unweighted case." @default.
