A direct proof of the weight retaining property of polynomials over a finite field
R.L.A. van Ravesteijn, C. de Vroedt · IEEE Transactions on Information Theory · 1988
A result of J.L. Massey et al. (see ibid., vol.IT-19, no.1, p.101-110, 1973) concerning weights of polynomials over GF(p/sup r/) is generalized from p=2 to general prime p. This generalization makes it possible to directly establish several theorems about polynomial weights in a way that no longer relies on results from coding theory.>
