For f (X ) # Z[X], let D f (n) be the least positive integer k for which f (1), ..., f (n) are distinct modulo k. Several results have been proven about the function D f in recent years, culminating in Moree's characterization of D f (n) whenever f lies in a certain (large) subset of Z[X ] and n is
In this article, we extend the recently introduced concept of partially dual ribbon graphs to graphs. We then go on to characterize partial duality of graphs in terms of bijections between edge sets of corresponding graphs. This result generalizes a well-known result of J. Edmonds in which natural d
