Modular forms of half-integral weight on Γ0(4) with few nonvanishing coefficients modulo ℓ

open access: yesOpen Mathematics, 2022
Let kk be a nonnegative integer. Let KK be a number field and OK{{\mathcal{O}}}_{K} be the ring of integers of KK. Let ℓ≥5\ell \ge 5 be a prime and vv be a prime ideal of OK{{\mathcal{O}}}_{K} over ℓ\ell . Let ff be a modular form of weight k+12k+\frac{1}

Bounds for twisted symmetric square L-functions via half-integral weight periods

open access: yesForum of Mathematics, Sigma, 2020
We establish the first moment bound $$\begin{align*}\sum_{\varphi} L(\varphi \otimes \varphi \otimes \Psi, \tfrac{1}{2}) \ll_\varepsilon p^{5/4+\varepsilon} \end{align*}$$ for triple product L-functions, where $\Psi $ is a fixed Hecke ...

On the algebraicity of coefficients of half-integral weight mock modular forms

open access: yesOpen Mathematics, 2018
Extending works of Ono and Boylan to the half-integral weight case, we relate the algebraicity of Fourier coefficients of half-integral weight mock modular forms to the vanishing of Fourier coefficients of their shadows.

On the Fourier expansions of Jacobi forms of half-integral weight

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2006
Using the relationship between Jacobi forms of half-integral weight and vector valued modular forms, we obtain the number of components which determine the given Jacobi form of index p, p2 or pq, where p and q are odd primes.

On the Fourier expansions of Jacobi forms

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2004
We use the relationship between Jacobi forms and vector-valued modular forms to study the Fourier expansions of Jacobi forms of indexes p, p2, and pq for distinct odd primes p, q.

Cycle integrals and rational period functions for Γ0+(2) and Γ0+(3)

open access: yesOpen Mathematics
For p∈{2,3}p\in \left\{2,3\right\} and an even integer kk, let Wk−2−(p){W}_{k-2}^{-}\left(p) be the space of period polynomials of weight k−2k-2 on Γ0+(p){\Gamma }_{0}^{+}\left(p) with eigenvalue −1-1 under the Fricke involution.
