Hachimori–Lim rank-growth conjecture for elliptic curves over imaginary quadratic fields

At least 4 years old · documented by

Let EE be an elliptic curve over an imaginary quadratic field FF satisfying the conditions stated in the source, and let F(n)F^{(n)} and Fcyc⁡F_{\operatorname{cyc}} denote the corresponding layers and cyclotomic extension. Hachimori–Lim's rank-growth conjecture. The conjecture asserts that

rank⁡E(F(n))≤rank⁡E(Fcyc⁡)pn.\operatorname{rank} E(F^{(n)})\leq \operatorname{rank} E(F_{\operatorname{cyc}})p^n.

This is identified in the source as a special case of a conjecture of Hachimori and Lim. The supplied passage does not state whether the conjecture has been resolved.
