我们证明,某些阶的挠点不在由方程 $y^2=x^{2g+1}+x$ 和 $g \geq 2$ 给出的超椭圆曲线雅可比变体的 theta 除数上。证明采用了安德森的方法,他证明了素数费马曲线的循环商的类似结果。
We show that torsion points of certain orders are not on a theta divisor in the Jacobian variety of a hyperelliptic curve given by the equation $y^2=x^{2g+1}+x$ with $g \geq 2$. The proof employs a method of Anderson who proved an analogous result for a cyclic quotient of a Fermat curve of prime degree.
