Fast computation of half-integral weight modular forms [PDF]
To study statistical properties of modular forms, including for instance Sato-Tate like problems, it is essential to have a large number of Fourier coefficients. In this article, we exhibit three bases for the space of modular forms of any half-integral weight and level 4, which have the property that many coefficients can be computed (relatively ...

Periodicities for Taylor coefficients of half-integral weight modular forms [PDF]
Congruences of Fourier coefficients of modular forms have long been an object of central study. By comparison, the arithmetic of other expansions of modular forms, in particular Taylor expansions around points in the upper-half plane, has been much less studied. Recently, Romik made a conjecture about the periodicity of coefficients around $τ=i$ of the

Coefficients of half-integral weight modular forms [PDF]
Inspired by Kolyvagin's celebrated work on the Birch and Swinnerton-Dyer Conjecture and works of Waldspurger, Kohnen and Zagier relating the Fourier coefficients of half-integral weight Hecke eigenforms to values of modular \(L\)-functions (there have been a number of works on the indivisibility of the coefficients of half-integral weight modular forms)

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

On “good” half-integral weight modular forms [PDF]
The authors prove a result on the nonvanishing of Fourier coefficients of modular forms of half-integral weight. Recently, there have been quite a few papers in this field by, among others, \textit{J. Bruinier} [Abh. Math. Sem. Univ. Hamb. 68, 163--168 (1998; Zbl 0954.11016)] and \textit{K. Ono} [C. R. Math.

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

SIGN OF FOURIER COEFFICIENTS OF MODULAR FORMS OF HALF‐INTEGRAL WEIGHT [PDF]
We establish lower bounds for (i) the numbers of positive and negative terms and (ii) the number of sign changes in the sequence of Fourier coefficients at squarefree integers of a half-integral weight modular Hecke eigenform.
