Abstract

Let π\pi be a fixed Hecke–Maass cusp form for SL(3,Z)\mathrm{SL}(3,\mathbb{Z}) and χ\chi be a primitive Dirichlet character modulo MM, which we assume to be a prime. Let L(s,πχ)L(s,\pi\otimes \chi) be the LL-function associated to πχ\pi\otimes \chi. For any given ε>0\varepsilon > 0, we establish a subconvex bound L(1/2+it,πχ)π,ε(M(t+1))3/41/36+εL(1/2+it, \pi\otimes \chi)\ll_{\pi, \varepsilon} (M(|t|+1))^{3/4-1/36+\varepsilon}, uniformly in both the MM- and tt-aspects.
