A note on the spaces of Eisenstein series on general congruence subgroups

Soumyadip Sahu

This article proposes a new approach to studying the spectral Eisenstein series of weight $k$ on a congruence subgroup of $SL_{2} (Z)$ using Hecke's theory of Eisenste…

Supersingular primes and Bogomolov property

Soumyadip Sahu

Let $E$ be an elliptic curve over a number field $K$ with at least one real embedding and $L$ be a finite extension of $K$ . We generalize a result of Habegger to show that $L(E_{\t…
