证明了若xm + axn置换素域Fp,其中m > n > 0且a ∈ F * p,则gcd(m-n,p-1)> n/p-1.相反,我们证明了如果q > 4且m > n > 0是固定的并且满足gcd(m-n,q-1)> 2 q(log log q)/ log q,则F q上存在形式为xm + ax n的置换二项式当且仅当gcd(m,n,q - 1)= 1。
We prove that if x m + ax n permutes the prime field F p , where m > n > 0 and a ∈ F * p , then gcd(m - n,p ― 1) > √/p ― 1. Conversely, we prove that if q > 4 and m > n > 0 are fixed and satisfy gcd(m - n, q ― 1) > 2q(log log q)/ log q, then there exist permutation binomials over F q of the form x m + ax n if and only if gcd(m, n, q - 1) = 1.
