Consider a connected network N. With each edge of N we associate a nonnegative real number called the length of the edge. Let N be a network obtained from N by adding new edges and/or by decreasing the lengths of some edges. For a generalized transmission number cf(N, v) defined on vertex v in N, we call Δc(v)=cf(N, v)-cf(N ,v) the Sabidussi difference of vertex v. In this note, we present a new theorem and its corollaries on the Sabidussi difference.
