关于给定迹和范数的元素个数的Katz界
On Katz's bound for number of elements with given trace and norm
摘要:
本文对具有给定迹和范数的有限域中元素个数的Katz界进行了改进。改进的方法是将问题归结为估计复曲面上的有理点的个数,然后利用Rojas-Leon和第二作者对复曲面上的上同调计算.
英文摘要:
In this note an improvement of the Katz's bound on the number of elements in a finite field with given trace and norm is given. The improvement is obtained by reducing the problem to estimating the number of rational points on certain toric Calabi-Yau hypersurface, and then to use detailed cohomological calculations by Rojas-Leon and the second author for such toric hypersurfaces.
