Abstract
Let E be a CM elliptic curve over the rationals and p > 3 a good ordinary prime for E. We show that Corank_(Z_p)Sel_(p^∞)(E/_Q) = 1 ⟹ ord_(s=1)L(s,E/_Q) = 1 for the p^∞-Selmer group Sel_(p^∞)(E/_Q) and the complex L-function L(s,E/_Q). In particular, the Tate–Shafarevich group X(E/_Q) is finite whenever corank_(Z_p)Selp^∞(E/_Q) = 1. We also prove an analogous p-converse for CM abelian varieties arising from weight two elliptic CM modular forms with trivial central character. For non-CM elliptic curves over the rationals, first general results towards such a p-converse theorem are independently due to Skinner (A converse to a theorem of Gross, Zagier and Kolyvagin, arXiv:1405.7294, 2014) and Zhang (Camb J Math 2(2):191–253, 2014).
