Determination of Hilbert modular forms using squarefree coefficients

Rishabh Agnihotri, Krishnarjun Krishnamoorthy

Let $F$ (over $Q$ ) be a totally real number field of narrow class number $1$ . We generalize a result of Kohnen on the determination of half integral weight modular forms b…

Primary rank of the class group of real cyclotomic fields

Rishabh Agnihotri, Kalyan Chakraborty, Mohit Mishra

Let $H = Q (ζ_{n} + ζ_{n}^{- 1})$ and $ℓ$ be an odd prime such that $q \equiv 1 (mod ℓ)$ for some prime factor $q$ of $n$ . We get a bound on the $ℓ$ -rank of the cl…
