On the $M_{H} (G)$ -property for Selmer groups at supersingular reduction

Sören Kleine, Ahmed Matar, Sujatha Ramdorai

Let $E$ be an elliptic curve defined over $Q$ which has good supersingular reduction at the odd prime $p$ . We study the variation of Iwasawa invariants and the $\mathfrak{…

Galois cohomology of elliptic curves over anticyclotomic extensions

Dac-Nhan-Tam Nguyen, Sujatha Ramdorai

Let $K$ be an imaginary quadratic field and $p$ be an odd prime number. Let $E / Q$ be an elliptic curve with good ordinary reduction at $p$ . We study the Iwasawa theory of…

Structure of fine Selmer groups in abelian p-adic Lie extensions

Debanjana Kundu, Filippo Alberto Edoardo Nuccio Mortarino Majno Di Capriglio, Sujatha Ramdorai

This paper studies fine Selmer groups of elliptic curves in abelian $p$ -adic Lie extensions. A class of elliptic curves are provided where both the Selmer group and the fine Selmer…
