Antipodal graphs and digraphs
The antipodal graph of a graph G, denoted by A(G), has the same vertex set as G with an edge joining vertices u and v if d(u,v) is equal to the diameter of G. (If G is disconnected, then diam G=∞.) This definition is extended to a digraph D where the arc (u,v) is included in A(D) if d(u,v) is the di...
