Explicit mock Heegner points and BSD formula on certain Mordell curves

Sumita Gunri, Somnath Jha, Dipramit Majumdar

For a natural number $a$ , let $E_{2 a}$ be the Mordell elliptic curve $X^{3} + Y^{3} = 2 a$ . We give an explicit construction of (mock) Heegner point on the Mordell curve $E_{2 p}$ for a pri…

On certain root number $1$ cases of the cube sum problem

Shamik Das, Somnath Jha

We consider certain families of integers $n$ determined by some congruence condition, such that the global root number of the elliptic curve $E_{- 432 n^{2}} : Y^{2} = X^{3} - 432 n^{2}$ is $1$ fo…

2-Selmer companion modular forms

Abhishek, Somnath Jha, Sudhanshu Shekhar

Let $N$ be a positive integer and $K$ be a number field. Suppose that $f_{1}, f_{2} \in S_{k} (Γ_{0} (N))$ are two newforms such that their residual Galois representations at $2$ are isomorph…

A $p$ -Converse theorem for Real Quadratic Fields

Muskan Bansal, Somnath Jha, Aprameyo Pal +1

Let $E$ be an elliptic curve defined over a real quadratic field $F$ . Let $p > 5$ be a rational prime that is inert in $F$ and assume that $E$ has split multiplicative reduction at…

$- 3$ -Selmer groups, ideal class groups and large $3$ -Selmer ranks

Somnath Jha, Dipramit Majumdar, Pratiksha Shingavekar

We consider the family of elliptic curves $E_{a, b} : y^{2} = x^{3} + a (x - b)^{2}$ with $a, b \in Z$ . These elliptic curves have a rational $3$ -isogeny, say $φ$ . We give an upper and a l…

Somnath Jha, Satyabrat Sahoo

Let $K$ be a totally real number field and $O_{K}$ be the ring of integers of $K$ . This manuscript examines the asymptotic solutions of the Fermat equation of signature $(…
