有限域F_(2~n)上的一些置换多项式（英文）

Some New Permutation Polynomials over F_(2~n)

给出有限域F2 n上形如f(x)=(x2 k+x+δ)s+x的多项式为置换多项式的几个充分条件.

Permutation polynomials have been studied for many years.In this paper that for any positive integers n and k with n ＞ k,fixed an element δ ∈ F2n,some sufficient conditions for polynomialf（x） =（x2k ＋ x ＋ δ）s ＋x to be a permutation polynomial over the finite field F2n are presented.
