Abstract

\((N,\gamma )\) -hyperelliptic semigroups were introduced by Fernando Torres to encapsulate the most salient properties of Weierstrass semigroups associated with totally ramified points of N-fold covers of curves of genus \(\gamma \) . Torres characterized \((2,\gamma )\) -hyperelliptic semigroups of maximal weight whenever their genus is large relative to \(\gamma \) . Here we do the same for \((3,\gamma )\) -hyperelliptic semigroups, and we formulate a conjecture about the general case whenever \(N \ge 3\) is prime.

$$(3,\gamma )$-hyperelliptic 曲线的权重边界
摘要 \((N,\gamma )\)-((N,\gamma))半群是由 Fernando Torres 提出的,它概括了与(((N,\gamma))属曲线的 N 个折叠盖的完全横切点相关的 Weierstrass 半群的最显著性质。托雷斯描述了 \((2,\gamma )\)-只要其属相对于 \(\gamma ) 是大的,就具有最大权重的双曲半群。在这里,我们对((3,\gamma )在这里,我们对 \((3,\gamma )\) -hyperelliptic semigroups 也做了同样的处理,并且我们对 \(N \ge 3\) 是素数的一般情况提出了一个猜想。
