Coates–Fukaya–Kato–Sujatha–Venjakob MH(G)M_H(G)-conjecture for signed Selmer groups

Let F/FF_{\infty}/F be the extension in the paper, let G=Gal(F/F)G=\operatorname{Gal}(F_{\infty}/F), and let HH be the subgroup specified by the extension, with completed group ring Zp[[H]]\mathbb{Z}_p[[H]]. For each choice of signs s{\vec{s}}, let Xs(E/F)X^{\vec{s}}(E/F_{\infty}) be the Pontryagin dual of the corresponding signed Selmer group, and let Xs(E/F)[p]X^{\vec{s}}(E/F_{\infty})[p^{\infty}] denote its pp-power torsion submodule. MH(G)\mathfrak{M}_H(G)-conjecture. For all choices of s{\vec{s}}, the module

Xs(E/F)/Xs(E/F)[p]X^{\vec{s}}(E/F_{\infty})/X^{\vec{s}}(E/F_{\infty})[p^{\infty}]

is finitely generated over Zp[[H]]\mathbb{Z}_p[[H]]. The source presents this as an extension of the MH(G)\mathfrak{M}_H(G)-conjecture to signed Selmer groups and states that it is not used in the subsequent calculations; no resolution is given.
