指数和
Examples
- Some exponential sums over primes in an arithmetic progression
算术级数中的一个指数和估计 - By making use of two kinds of exponential sums and cohen ' s sieve , we better the lower bound concerning the number of primitive elements and also prove the existence of primitive polynomials with a1 , a2 prescribed when n = 5 , 6 . in the remaining of the paper we study primitive elements in the form of a + a - 1 over finite fields . a counting formula is given as a result , as well as all the finite fields that do not have such elements
本文对n = 5 ， 6两种情形，利用有限域上的两类特征和估计及cohen筛法[ 5 ] [ 7 ] ，改进了[ 10 ] [ 11 ]中关于方程组本原元解个数的下界，并得到在特征为奇的有限域上存在可预先指定前两项系数的n次本原多项式。
