Abstract: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.
