Explicit Arithmetic of Jacobians of Generalized Legendre Curves Over Global Function Fields

Explicit Arithmetic of Jacobians of Generalized Legendre Curves Over Global Function Fields

We study the Jacobian $J$ of the smooth projective curve $C$ of genus $r-1$ with affine model $y^r = x^{r-1}(x + 1)(x + t)$ over the function field $\mathbb{F}_p(t)$, when $p$ is prime and $r\ge 2$ is an integer prime to $p$. When $q$ is a power of $p$ and …
