Abstract

Let denote the wheel graph having n-vertices. If i and j are any two vertices of , define Let D be the matrix with entry equal to . The matrix D is called the distance matrix of . Suppose is an odd integer. In this paper, we deduce a formula to compute the Moore-Penrose inverse of D. More precisely, we obtain an matrix and a rank one matrix such that Here, is positive semidefinite, and all row sums are equal to zero.
