Coates–Sujatha fine Selmer conjecture over cyclotomic extensions

Let ll be an odd prime, let FF be a number field, and let E\mathcal{E} be an elliptic curve over FF. For an extension L/FL/F in the maximal extension unramified outside the prescribed finite set of places, let Rl(E/L)R_{l^{\infty}}(\mathcal{E}/L) denote the fine ll^{\infty}-Selmer group. Let FcycF^{\mathrm{cyc}} be the cyclotomic Zl\mathbb{Z}_l-extension of FF. Coates–Sujatha's conjecture. The group Rl(E/Fcyc)R_{l^{\infty}}(\mathcal{E}/F^{\mathrm{cyc}}) is a cofinitely generated Zl\mathbb{Z}_l-module. This is the cyclotomic fine-Selmer finiteness conjecture attributed to Coates and Sujatha; the source uses it as the comparison point for the anticyclotomic analogue.
