Towards a generalized Maeda conjecture for modular forms with quadratic nebentypus

Debargha Banerjee, Dhrubajyoti Das, Srijan Das +2

We establish a lower bound for the number of non-CM Galois orbits of newforms in $S_{k} (N, Ψ)$ with non-trivial quadratic nebentypus $Ψ$ for sufficiently large weights. Extending the…

Monsky Matrix and 2-Selmer rank

Shamik Das, Sudipa Mondal

In this article, we produce infinite families of non-congruent numbers in the residue class of $1, 2,$ and $3$ modulo $8$ with arbitrarily many triples or quadruples prime factors.…

$2$ -Selmer groups, $2$ -class groups, and congruent numbers

Shamik Das, Debajyoti De, Sudipa Mondal

In this article, we study necessary conditions for certain square-free integers to be congruent numbers. Our method uses divisibility properties of class numbers of related imagina…

A necessary condition for a congruent number of the form $8 k + 3$

Shamik Das, Sudipa Mondal

A positive square-free integer is called a \textit{congruent number} if it arises as the area of a right triangle with rational side lengths. Let $n = p_{1} p_{2} \dots p_{t} q$ be a s…
