Abstract–In this article, some interesting applications of generalized inverses in the graph theory are revisited. Interesting properties of generalized inverses are employed to make the proof of several known results simpler, and several technique

Let T be a tree with vertex set {1, …, n} such that each edge is assigned a nonzero weight. The squared distance matrix of T, denoted by Δ, is the n × n matrix with (i, j)-element d(i, j)2, where d(i, j) is the sum of the weights of the edges on

In this paper, several existing results related to secondary transpose are critically reviewed and a result analogous to spectral decomposition theorem is obtained for a real secondary symmetric matrix. Noting that Moore–Penrose inverse with refere

Euclidean distance matrices (EDM) are symmetric nonnegative matrices with several interesting properties. In this article, we introduce a wider class of matrices called generalized Euclidean distance matrices (GDMs) that include EDMs. Each GDM is an

Let n ≥ 4 be an even integer and W n be the wheel graph with n vertices. The distance d i j between any two distinct vertices i and j of W n is the length of the shortest path connecting i and j. Let D be the n × n symmetric matrix with diagonal e

The four point theorem is a condition for distances to arise from trees. Based on this condition, for any tree T on n vertices, we associate an ( n 2 ) × ( n 2 ) matrix M T . We find the rank and the Smith Normal Form (SNF) of the matrix M T and sho
