关于二次扭的Watkins猜想

A conjecture of Watkins for quadratic twists

Jose A. Esparza-Lozano, Hector Pasten

摘要:

Watkins证明了对于Mordell-Weil秩为$r$的$\mathbb{Q}$上的椭圆曲线$E$,$E$的模次数可被$2^r$整除.若$E$具有非平凡有理$2$ -扭,则证明了关于$E$的所有二次扭都由具有足够多素因子的无平方整数生成的猜想.

英文摘要:

Watkins conjectured that for an elliptic curve $E$ over $\mathbb{Q}$ of Mordell-Weil rank $r$, the modular degree of $E$ is divisible by $2^r$. If $E$ has non-trivial rational $2$-torsion, we prove the conjecture for all the quadratic twists of $E$ by squarefree integers with sufficiently many prime factors.
