设p为奇素数,q = p m。设l是一个奇正整数。设p≡-1 (mod l)或p≡1 (mod l)和l | m。利用可视为广义Lucas序列的整数序列an = Σ (2cos π(2t -1) l) n,构造有限域F q的所有排列二项式p (x) = x r + x u。
Let p be an odd prime and q = p m . Let l be an odd positive integer. Let p ≡ -1 (mod l) or p ≡ 1 (mod l) and l | m. By employing the integer sequence a n = Σ (2cos π(2t - 1) l) n , which can be considered as a generalized Lucas sequence, we construct all the permutation binomials P(x) = x r + x u of the finite field F q .
