Abstract
Jo Heath and the author found a set of necessary and sufficient conditions for the existence of an exactly k‐to‐1 map from a graph G to a graph H. These conditions were all local ones. Here this result is used to give necessary and sufficient conditions for the existence of an exactly k‐to‐1 map from G to H when k is sufficiently large. The conditions for this are global in nature. © 1993 John Wiley & Sons, Inc.
