The MH(G)\mathfrak{M}_H(G)-conjecture for Selmer groups over pp-adic Lie extensions

Let F/FF_\infty/F be a strongly admissible pp-adic Lie extension, set G=Gal(F/F)G=\operatorname{Gal}(F_\infty/F) and H=Gal(F/Fcyc)H=\operatorname{Gal}(F_\infty/F^{\mathrm{cyc}}), and let X(E/F)X(E/F_\infty) be the Pontryagin dual of the Selmer group. Define

Xf(E/F):=X(E/F)/X(E/F)[p].X_f(E/F_\infty):=X(E/F_\infty)/X(E/F_\infty)[p^\infty].

The MH(G)\mathfrak{M}_H(G)-conjecture. The module X(E/F)X(E/F_\infty) lies in MH(G)\mathfrak{M}_H(G); equivalently, Xf(E/F)X_f(E/F_\infty) is finitely generated over Zp[[H]]\mathbb{Z}_p[[H]]. This condition enables the algebraic KK-theoretic construction of characteristic elements; the source gives no resolution status.
