Lifting Congruences to weight 3/2

Neil Dummigan, Srilakshmi Krishnamoorthy

Given a congruence of Hecke eigenvalues between newforms of weight $2$ , we prove, under certain conditions, a congruence between corresponding weight- $3/2$ forms.

A note on the Fourier coefficients of a Cohen-Eisenstein series

Srilakshmi Krishnamoorthy

We prove a formula for the coefficients of a weight $3/2$ Cohen-Eisenstein series of square-free level $N$ . This formula generalizes a result of Gross and in particular, it proves…

On sign changes for almost prime coefficients of half-integral weight modular forms

Srilakshmi Krishnamoorthy, M. Ram Murty

For a half-integral weight modular form $f = \sum_{n = 1}^{\infty} a_{f} (n) n^{\frac{k - 1}{2}} q^{n}$ of weight $k = l + \frac{1}{2}$ on $Γ_{0} (4)$ such that $a_{f} (n)$ ( $n$ $\in$ $N$ )…

The Eisenstein elements of modular symbols for level product of two distinct odd primes

Srilakshmi Krishnamoorthy, Debargha Banerjee

We explicitly write down the Eisenstein elements inside the space of modular symbols for Eisenstein series with integer coefficients for the congruence subgroups Γ_0 (pq) with p an…
