Refined conjectures on Fitting ideals of BDP Selmer groups

Chan-Ho Kim, Aprameyo Pal, Jishnu Ray

Under mild assumptions, we prove the strong main conjecture for BDP Selmer groups of elliptic curves with good reduction in the sense of Kurihara's refined Iwasawa theory. In parti…

Euler systems and the symmetric square of a Hida family

Debanjana Kundu, Jishnu Ray, Stefano Vigni

Let $p \geq 7$ be a prime number. We build a non-trivial Euler system for the symmetric square of a $p$ -adic Hida family of modular forms interpolating the Euler system constructed b…

Iwasawa invariants of Bertolini--Darmon theta elements

Abhishek, Jishnu Ray, Pronay Kumar Karmakar

In this article we study the Iwasawa invariants of Bertolini--Darmon theta elements in the anticyclotomic $Z_{p}$ -extension of an imaginary quadratic field $K$ for weight tw…

Explicit isomorphisms for a Herr-type complex over a metabelian extension

Anand Chitrao, Aditya Karnataki, Jishnu Ray

Let $S$ be a Banach algebra over $Q_{p}$ whose residue fields are finite extensions of $Q_{p}$ . Given an arithmetic family $V$ of Galois representations, i.e., a fini…
