The Distance Matrices of Some Graphs Related to Wheel Graphs

Let D denote the distance matrix Long Sleeve of a connected graph G.The inertia of D is the triple of integers (n+(D), n0(D), n-(D)), where n+(D), n0(D), and n-(D) denote the number of positive, 0, and negative eigenvalues of D, respectively.In this paper, we mainly study the inertia of distance matrices of some graphs related to wheel graphs and g
