Local Heegner-point infinitude conjecture

From papers

Let KK be an imaginary quadratic field, let p5p\geq 5 be a prime, let EE be an elliptic curve over Q\mathbb{Q} with modular parametrization π\pi, and let K/KK_{\infty}/K be the anticyclotomic Zp\mathbb{Z}_p-extension. For a prime p\mathfrak{p}_{\infty} of KK_{\infty} above pp, write KpK_{\mathfrak{p}_{\infty}} for the union of the corresponding completions, and let αn\alpha_n be the Heegner points. The local Heegner-point infinitude conjecture. Suppose that (E,π,p)(E,\pi,p) satisfies ()(*). If EE has ordinary reduction at pp, there exists a prime p\mathfrak{p}_{\infty} above pp such that the Γ\Gamma-submodule of E(Kp)/pE(K_{\mathfrak{p}_{\infty}})/p generated by the αn\alpha_n has infinite cardinality. If EE has supersingular reduction at pp and pp splits in K/QK/\mathbb{Q}, there exists a prime p\mathfrak{p}_{\infty} above pp such that each of the Γ\Gamma-submodules generated by the even-indexed points α2n\alpha_{2n} and by the odd-indexed points α2n+1\alpha_{2n+1} has infinite cardinality. The source presents this as a third conjecture and later uses its supersingular part to derive consequences for Selmer groups; no proof of the full statement is given.
