广义Weierstrass半群与一类分离变量曲线的Riemann-Roch空间

Generalized Weierstrass semigroups and Riemann-Roch spaces for certain curves with separated variables

Wanderson Tenório, Guilherme Tizziotti

摘要:

本文研究了广义Weierstrass半群$\widehat{H} (\mathbf{P}_m)$在某些曲线上有理点的$m$ -元组$\mathbf{P}_m = (P_{1}, \ldots , P_{m})$上的情形,其中$f(y) = g(x)$是$\mathbb{F}_{q}$上的平面模型,其中${f(T),g(T)\in \mathbb{F}_q[T]}$ .特别是,我们计算的生成集$\widehatΓ(\mathbf{P}_m)$的$\widehat{H} (\mathbf{P}_m)$,因此,我们明确的基础上的Riemann-Roch空间的因子与支持$\{P_{1}, \ldots , P_{m}\}$在这些曲线,推广Maharaj,马修斯和Pirsic的结果。

英文摘要:

In this work we study the generalized Weierstrass semigroup $\widehat{H} (\mathbf{P}_m)$ at an $m$-tuple $\mathbf{P}_m = (P_{1}, \ldots , P_{m})$ of rational points on certain curves admitting a plane model of the form $f(y) = g(x)$ over $\mathbb{F}_{q}$, where ${f(T),g(T)\in \mathbb{F}_q[T]}$. In particular, we compute the generating set $\widehatΓ(\mathbf{P}_m)$ of $\widehat{H} (\mathbf{P}_m)$ and, as a consequence, we explicit a basis for Riemann-Roch spaces of divisors with support in $\{P_{1}, \ldots , P_{m}\}$ on these curves, generalizing results of Maharaj, Matthews, and Pirsic.
