On the control theorem for fine Selmer groups and the growth of fine Tate-Shafarevich groups in -extensions

Meng Fai Lim

Let be an abelian variety defined over a number field . We prove a control theorem for the fine Selmer group of the abelian variety which essentially says that the kerne…

On the algebraic functional equation of the eigenspaces of mixed signed Selmer groups of elliptic curves with good reduction at primes above

Suman Ahmed, Meng Fai Lim

Let be an odd prime number, and let be an elliptic curve defined over a number field which has good reduction at every prime above . Under suitable assumptions, we prove…

On the signed Selmer groups of congruent elliptic curves with semistable reduction at all primes above

Suman Ahmed, Meng Fai Lim

Let be an odd prime. We attach appropriate signed Selmer groups to an elliptic curve , where is assumed to have semistable reduction at all primes above . We then com…

On the Euler characteristics of signed Selmer groups

Suman Ahmed, Meng Fai Lim

Let be an odd prime number, and an elliptic curve defined over a number field with good reduction at every prime of above . In this short note, we compute the Euler…
