Abstract

Let E/Q be a CM elliptic curve and p a prime of good ordinary reduction for E. We show that if Sel_(p∞) (E/Q) has Zₚ-corank one, then E(Q) has a point of infinite order. The non-torsion point arises from a Heegner point, and thus ordₛ₌₁ L(E,s) = 1, yielding a p-converse to a theorem of Gross–Zagier, Kolyvagin, and Rubin in the spirit of [49, 54]. For p > 3, this gives a new proof of the main result of [12], which our approach extends to all primes. The approach generalizes to CM elliptic curves over totally real fields [4].
