研究了超椭圆曲线的Jacobian的自同构分解。对于方程为y^n=f(x^m)的曲线,我们给出了由曲线的自同构引起的雅可比矩阵分解的m和n的充分必要条件。此外,我们推广了一类非超椭圆曲线$\mathcal X_{r,s} $在\cite{Ya}中的构造,并确定了Jacobian $\mbox{Jac}(\mathcal X_{r,s})$可分解的关于r$和s$的算术条件.
We investigate the decomposition of Jacobians of superelliptic curves based on their automorphisms. For curve with equation $y^n=f(x^m)$ we provide an necessary and sufficient condition in terms of $m$ and $n$ for the decomposition of the Jacobian induced by the automorphisms of the curve. Moreover, we generalize a construction in \cite{Ya} of a family of non-hyperelliptic curves $\mathcal X_{r,s} $ and determine arithmetic conditions on $r$ and $s$ that the Jacobians $\mbox{Jac} (\mathcal X_{r, s})$ decomposes.
