Torsion of Rational Elliptic Curves over the Cyclotomic Extensions of $\mathbb{Q}$

Abstract: Let $E$ be an elliptic curve defined over $\Q$. Let $p>3$ be a prime such that $p-1$ is not divisible by $3,4,5,7,11$. In this article we classify the groups that can arise as $E(\mathbb{Q}(\zeta_p))_{\text{tors}}$ up to isomorphism. The method illustrates techniques for eliminating possible structures that can appear as a subgroup of $E(\mathbb{Q}^{ab})_{\text{tors}}.$
