On the Pseudonullity of Fine Selmer groups over function fields

Sohan Ghosh

The $p^{\infty}$ -fine Selmer group of an elliptic curve $E$ over a global field is a subgroup of the classical $p^{\infty}$ -Selmer group. Coates and Sujatha discovered that the structu…

Iwasawa theory of fine Selmer groups over global fields

Sohan Ghosh, Somnath Jha, Sudhanshu Shekhar

The $p^{\infty}$ -fine Selmer group of an elliptic curve $E$ over a number field $F$ is a subgroup of the classical $p^{\infty}$ -Selmer group of $E$ over $F$ . Fine Selmer group is close…

Twisting lemma for $Λ$ -adic modules

Sohan Ghosh, Somnath Jha, Sudhanshu Shekhar

A classical twisting lemma says that given a finitely generated torsion module $M$ over the Iwasawa algebra $Z_{p} [[Γ]]$ with $Γ ≅ Z_{p}, \exists$ a continuous c…
