On Fourier coefficients of modular forms of half integral weight at squarefree integers
We show that the Dirichlet series associated to the Fourier coefficients of a half-integral weight Hecke eigenform at squarefree integers extends analytically to a holomorphic function in the
Bounds for Siegel Modular Forms of genus 2 modulo $p$
Sturm obtained the bounds for the number of the first Fourier coefficients of elliptic modular form $f$ to determine vanishing of $f$ modulo a prime $p$. In this paper, we study analogues of Sturm's
Arithmetic properties of coefficients of half-integral weight Maass–Poincaré series
Zagier [23] proved that the generating functions for the traces of level 1 singular moduli are weight 3/2 modular forms. He also obtained generalizations for “twisted traces”, and for traces of
Fourier Coefficients of Modular Forms of Half-Integral Weight in Arithmetic Progressions
We study the probabilistic behavior of sums of Fourier coefficients in arithmetic progression. We prove a result analogous to previous work of Fouvry-GangulyKowalski-Michel and Kowalski-Ricotta in
Modular forms of half-integral weight with few non-vanishing coefficients modulo ℓ
Bruinier and Ono classified cusp forms of half-integral weight F(z):=∞Σn=0a(n)q n ∈ S λ+1 2 (Γ 0 (N), Χ )∩Z[[q]] whose Fourier coefficients are not well distributed for modulo odd primes l. Ahlgren
Singular moduli of higher level and special cycles
We describe the complex multiplication (CM) values of modular functions for $$\Gamma _0(N)$$Γ0(N) whose divisor is given by a linear combination of Heegner divisors in terms of special cycles on the
Sturm type theorem for Siegel modular forms of genus 2 modulo p
Suppose that f is an elliptic modular form with integral coefficients. Sturm obtained in (14) bounds for a nonnegative integer n such that every Fourier coefficient of f vanishes modulo a prime p if
Congruences for the coefficients of weakly holomorphic modular forms
Recent works have used the theory of modular forms to establish linear congruences for the partition function and for traces of singular moduli. We show that this type of phenomenon is completely
