Coates–Fukaya–Kato–Sujatha–Venjakob finiteness conjecture

Let KK be a number field, let pp be a prime, let EE be an elliptic curve over KK, and let L/KL/K be a Galois extension with G=Gal(L/K)G=\operatorname{Gal}(L/K) containing a closed normal subgroup HH such that G/HZpG/H\cong {\mathbb Z}_p. Write Λ(G)=Zp[[G]]\operatorname{\Lambda}(G)={\mathbb Z}_p[[G]], let X(E/L)X(E/L) be the Pontryagin dual of the Selmer group, and let X(E/L)(p)X(E/L)(p) be its maximal pp-power-torsion submodule. Coates–Fukaya–Kato–Sujatha–Venjakob conjecture. If EE has ordinary reduction at every prime of KK over pp, then X(E/L)/X(E/L)(p)X(E/L)/X(E/L)(p) is a finitely generated Λ(H)\operatorname{\Lambda}(H)-module. This finiteness condition is the stronger hypothesis used to construct noncommutative algebraic pp-adic LL-functions in the cited formalism. The source states it as conjectural and gives no resolution in the stated generality.
