三次曲面上的有理点和Norm-Trace曲线上的AG码

Rational points on cubic surfaces and AG codes from the Norm-Trace curve

Matteo Bonini, Massimiliano Sala, Lara Vicino

摘要:

本文给出了$\mathbb{F}_{q^3}$上的Norm-Trace曲线与$y=ax^3+bx^2+cx+d$形式的曲线相交的完全刻画,推广了Bonini和Sala的一个结果,并提供了由这类曲线产生的单点AG码的重量谱的更详细的信息.我们还得到,与明确的计算,一些一般的界限上定义的三次曲面上的有理点的数量在$\mathbb{F}_{q}$。

英文摘要:

In this paper we give a complete characterization of the intersections between the Norm-Trace curve over $\mathbb{F}_{q^3}$ and the curves of the form $y=ax^3+bx^2+cx+d$, generalizing a previous result by Bonini and Sala, providing more detailed information about the weight spectrum of one-point AG codes arising from such curve. We also derive, with explicit computations, some general bounds for the number of rational points on a cubic surface defined over $\mathbb{F}_{q}$.
