In [14], D. Skabelund constructed a maximal curve over as a cyclic cover of the Suzuki curve. In this paper we explicitly determine the structure of the Weierstrass semigroup at any point P of the Skabelund curve. We show that its Weierstrass points are precisely the -rational points. Also we show that among the Weierstrass points, two types of Weierstrass semigroup occur: one for the -rational points, one for the remaining -rational points. For each of these two types its Apéry set is computed as well as a set of generators.

Skabelund最大曲线上的Weierstrass半群
在[14]中,D。Skabelund构造了一条最大曲线 作为铃木曲线的周期性覆盖。在本文中,我们明确确定了Skabelund曲线的任意P点处的Weierstrass半群的结构。我们证明它的Weierstrass点正好是-理性点。我们还表明,在Weierstrass点中,出现两种类型的Weierstrass半群:一种为-理性点,剩余的一个 -理性点。对于这两种类型中的每一种,都会计算其Apéry集以及一组生成器。
