Given a half-integral weight holomorphic Kohnen newform $f$ on $\Gamma_0(4)$, we prove an asymptotic formula for large primes $p$ with power saving error term for \begin{equation*} \sideset{}{^*} \sum_{\chi \hspace{-0.15cm} \pmod{p}} \big | L(1/2,f,\chi) \big |^2. \end{equation*} Our result is unconditional, it does not rely on the Ramanujan-Petersson conjecture for the form $f$. There are two main inputs. The first is a careful spectral analysis of a highly unbalanced shifted convolution…

### On the distribution of modular square roots of primes

• Mathematics
• 2020
We use recent bounds on bilinear sums with modular square roots to study the distribution of solutions to congruences $x^2 \equiv p \pmod q$ with primes $p\le P$ and integers $q \le Q$. This can be

### The non-vanishing of central values of automorphic L-functions and Landau-Siegel zeros

• Mathematics
• 2000
We describe a number of results and techniques concerning the non-vanishing of automorphic L-functions at s = ½. In particular we show that as N → ∞ at least 50% of the values L(½, f), with f varying

### A Burgess-like subconvex bound for twisted L-functions

• Mathematics
• 2007
Abstract Let g be a cuspidal newform (holomorphic or Maass) of arbitrary level and nebentypus, χ a primitive character of conductor q, and s a point on the critical line ℜs = ½. It is proved that ,

### On the Fourth Power Moment of the Riemann Zeta-Function

• Mathematics
• 1995
Abstract The function E 2 ( R ) is used to denote the error term in the asymptotic formula for the fourth power moment of the Riemann zeta-function on the half-line. In this paper we prove several

### Quantum unique ergodicity for half-integral weight automorphic forms

We investigate the analogue of the Quantum Unique Ergodicity (QUE) conjecture for half-integral weight automorphic forms. Assuming the Generalized Riemann Hypothesis (GRH) we establish QUE for both
