Abstract:
In this paper, we consider the family $\{L_j(s)\}_{j=1}^{\infty }$ of $L$-functions associated to an orthonormal basis $\{u_j\}_{j=1}^{\infty }$ of even Hecke–Maass forms for the modular group $\operatorname {SL}(2,\mathbb Z)$ with eigenvalues $\{\lambda _j=\kappa _{j}^{2}+1/4\}_{j=1}^{\infty }$. We prove the following effective non-vanishing result: At least $50 \%$ of the central values $L_j(1/2)$ with $\kappa _j \leq T$ do not vanish as $T\rightarrow \infty$. Furthermore, we establish effective non-vanishing results in short intervals.References
