关于有限域上的二次曲线

On quadratic curves over finite fields

Vagn Lundsgaard Hansen, Andreas Aabrandt

摘要:

有限域上代数曲线的几何是一个丰富的研究领域。在以前的工作中,作者研究了经典单位圆的有限域上几何的一个特殊方面,即圆方程的解的个数如何依赖于有限域$\mathbb{F}_{p^n}$的特征$p$和度$n\geq 1$.本文对经典圆锥曲线的二元二次方程所定义的二次曲线在有限域上的几何作了类似的研究。特别是二次方程的混合项是有趣的,我们的结果显示了丰富的各种可能性的解决方案,这个方程的数量在有限域。

英文摘要:

The geometry of algebraic curves over finite fields is a rich area of research. In previous work, the authors investigated a particular aspect of the geometry over finite fields of the classical unit circle, namely how the number of solutions of the circle equation depends on the characteristic $p$ and the degree $n\geq 1$ of the finite field $\mathbb{F}_{p^n}$. In this paper, we make a similar study of the geometry over finite fields of the quadratic curves defined by the quadratic equations in two variables for the classical conic sections. In particular the quadratic equation with mixed term is interesting, and our results display a rich variety of possibilities for the number of solutions to this equation over a finite field.
