Let 1=(X, R) denote a distance-regular graph with distance function and diameter d 4. By a parallelogram of length i (2 i d), we mean a 4-tuple xyzu of vertices in X such that (x, y)= (z, u)=1, (x, u)=i, and (x, z)= ( y, z)= ( y, u)=i&1. We prove the following theorem. Theorem. Let 1 denote a distan

Let Ξ be a regular graph with n vertices, diameter D, and d + 1 In a previous paper, the authors showed that if P (Ξ») > n -1, then D β€ d -1, where P is the polynomial of degree d-1 which takes alternating values Β±1 at Ξ» 1 , . . . , Ξ» d . The graphs satisfying P (Ξ») = n -1, called boundary graphs, h
This report considers the resistance distance as a recently proposed new ## Ε½ . intrinsic metric on molecular graphs, and in particular, the sum R over resistance distances between all pairs of vertices is considered as a graph invariant. It has been vertices and K denotes a complete graph contai
