On the classification of small cyclotomic integers

Jitendra Bajpai, Srijan Das, Kiran S. Kedlaya +1

We give a general classification theorem for cyclotomic algebraic integers with all complex absolute values bounded by a fixed constant $c$ , modeled on the theorem of Cassels which…

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…

A note on extensions of $p$ -adic representations of $GL_{2} (Q_{p})$

Debargha Banerjee, Srijan Das

We compute extension groups in the category of duals of $p$ -adic Banach space representations of $GL_{2} (Q_{p})$ . Focusing on representations arising from the $p$ -adi…

The exceptional set in Cassel's theorem on small cyclotomic integers

Jitendra Bajpai, Srijan Das, Kiran S. Kedlaya +4

In a 1965 paper, R. Robinson made five conjectures about the classification of cyclotomic algebraic integers for which the maximum absolute value in any complex embedding (the hous…
