Consider the hyperelliptic curves defined over , and their Jacobians . Without loss of generality a is a non-zero 8th power free integer. Our aim is to obtain upper bounds for . In particular, we would like to find infinite subfamily of with rank 0. We show that under certain assumptions on the quartic field , (if ), and (if ) where is the number of distinct prime divisors of m. We also generalize this result to the ranks of the Jacobians of . Moreover, we prove that if is a prime then , , and if then , and consequently for such primes. We also make numerical computations of ranks and rational points, and put a few conjectures.

考虑超椭圆曲线 定义结束 和他们的雅各布主义者 。在不失一般性的前提下,a是一个非零的8次幂无整数。我们的目标是为。特别是,我们想找到的无限亚科 等级为0。我们证明在某些假设下对四次场 , (如果 ),以及 (如果 )哪里 是m的不同素数除数的数量。我们还将这个结果推广到。此外,我们证明 那是素数 , , 而如果 然后 , 因此 对于这样的素数。我们还对等级和有理点进行了数值计算,并提出了一些猜想。
