$GL(3)$上扭曲$L$-函数的混合次凸性界

Hybrid subconvexity bounds for twisted $L$-functions on $GL(3)$

Bingrong Huang

摘要:

设$q$是一个大素数,$χ$是模$q$的二次特征标。设$ϕ$是$SL(3,\mathbb{Z})$的自对偶Hecke-Maass尖点形式,$u_j$是$Γ_0(q)\subseteq SL(2,\mathbb{Z})$的具有谱参数$t_j$的Hecke-Maass尖点形式.证明了扭曲$L$-函数\[ L(1/2,ϕ\times u_j\timesχ)\ll_{ϕ,\varepsilon} (qt_j)^{3/2-θ+\varepsilon},\quad L(1/2+it,ϕ\timesχ)\ll_{ϕ,\varepsilon} (qt)^{3/4-θ/2+\varepsilon}, \]对任意$\varepsilon>0$的混合次凸性界,其中$θ=1/23$是容许的.

英文摘要:

Let $q$ be a large prime, and $χ$ the quadratic character modulo $q$. Let $ϕ$ be a self-dual Hecke--Maass cusp form for $SL(3,\mathbb{Z})$, and $u_j$ a Hecke--Maass cusp form for $Γ_0(q)\subseteq SL(2,\mathbb{Z})$ with spectral parameter $t_j$. We prove the hybrid subconvexity bounds for the twisted $L$-functions \[ L(1/2,ϕ\times u_j\timesχ)\ll_{ϕ,\varepsilon} (qt_j)^{3/2-θ+\varepsilon},\quad L(1/2+it,ϕ\timesχ)\ll_{ϕ,\varepsilon} (qt)^{3/4-θ/2+\varepsilon}, \] for any $\varepsilon>0$, where $θ=1/23$ is admissible.
