关于包含Thas'不变量的超曲面的两个上界
On two upper bounds for hypersurfaces involving a Thas' invariant
摘要:
设$X^n$是$\mathbb{P}^{n+1}$中的一个超曲面,其中$n\geq 1$定义在由$q$元素组成的有限域$\mathbb{F}_q$上.本文在射影等价的前提下,对超曲面$X^n$进行了分类,得到了包含Thas不变量的$X^n$上的$\mathbb{F}_q$ -点的个数达到两个初等上界的超曲面$X^n$.
英文摘要:
Let $X^n$ be a hypersurface in $\mathbb{P}^{n+1}$ with $n\geq 1$ defined over a finite field $\mathbb{F}_q$ of $q$ elements. In this note, we classify, up to projective equivalence, hypersurfaces $X^n$ as above which reach two elementary upper bounds for the number of $\mathbb{F}_q$-points on $X^n$ which involve a Thas' invariant.
