摘要:

本文考虑有限域$\mathbb{F}_q$上的加权射影空间中给定次数的超曲面上的$\mathbb{F}_q$ -有理点的最大数目,即给定次数的加权齐次多项式在$\mathbb{F}_q$上相应的加权射影空间中的零点的最大数目.在经典射影空间的情况下,这个问题已经由J. - P. Serre。在加权射影空间的情形下,我们给出了一些结构和部分结果。应用到编码理论包括和附录提供了一个简短的纲要有关加权射影空间的结果也包括在内。

英文摘要:

We consider the question of determining the maximum number of $\mathbb{F}_q$-rational points that can lie on a hypersurface of a given degree in a weighted projective space over the finite field $\mathbb{F}_q$, or in other words, the maximum number of zeros that a weighted homogeneous polynomial of a given degree can have in the corresponding weighted projective space over $\mathbb{F}_q$. In the case of classical projective spaces, this question has been answered by J.-P. Serre. In the case of weighted projective spaces, we give some conjectures and partial results. Applications to coding theory are included and an appendix providing a brief compendium of results about weighted projective spaces is also included.
