The Chevalley–Warning Theorem is a result on the solution set of a system of polynomial equations in variables over a finite field in the low degree case . In this note we reformulate that result in terms of fibers of the associated polynomial map and, following Heath-Brown, show that something weaker continues to hold when . This result invites a search for homogeneous degree polynomials in variables over for which the associated polynomial function is not surjective, and we exhibit several families of such polynomials.

Chevalley-Warning 定理是多项式方程组的解集的结果 在 有限域上的变量 在低度的情况下 . 在本笔记中,我们根据相关多项式映射的纤维重新表述该结果,并遵循 Heath-Brown,表明当较弱的东西继续成立时. 此结果邀请搜索同质度 多项式 变数结束 其中相关的多项式函数 不是满射的,我们展示了几个这样的多项式族。
