Weights Modulo a Prime Power in Divisible Codes and a Related Bound

In this paper, we generalize the theorem given by R. M. Wilson about weights modulo p^t in linear codes to a divisible code version. Using a similar idea, we give an upper bound for the dimension of a divisible code by some divisibility property of its weight enumerator modulo p^e. We also prove that this bound implies Ward´s bound for divisible codes. Moreover, we see that in some cases, our bound gives better results than Ward´s bound
