WebThe following are our two main results, which describe necessary and sufficient conditions for f n (x) and g n (x) being permutations over F p. Theorem 1. For a prime p and a nonnegative integer n, f n (x) is a permutation polynomial over F p if and only if n ≡ 1 or − 2 (mod p (p 2 − 1) 2). Next we show that f n (x) and g n (x) have the ...

Given a prime p and an integer n, we denote the Legendre symbol of n with respect to p by (n p). WebTheorem 18. Let f(x) be a monic polynomial in Z[x]. In other words, f(x) has integer coefﬁcients and leading coefﬁcient 1. Let p be a prime, and let n = degf. Then the congruence f(x) 0 (mod p) has at most n incongruent roots modulo p. Proof. If n = 0, then, since f(x) is monic, we have f(x) = 1 . In this case, f(x) has 0
