Wuthrich's μ–λ conjecture for fine Selmer groups

Let E/QE/\mathbb{Q} be an elliptic curve, let pp be a prime of good reduction, and let Rp(E/Qcyc)\mathcal{R}_{p^\infty}(E/\mathbb{Q}_{\operatorname{cyc}}) be the fine Selmer group over the cyclotomic Zp\mathbb{Z}_p-extension. Wuthrich's μ–λ conjecture. For all but finitely many such primes pp,

μ=0andλ=max{rankE(Q)1,0}.\mu=0\qquad\text{and}\qquad \lambda=\max\{\operatorname{rank}E(\mathbb{Q})-1,0\}.

This is the source's reformulation of Wuthrich's conjecture; it is open in general, and the source proves only a conditional implication in rank zero.
