Strong Subconvexity for Self-Dual GL(3) L-Functions


In this paper, we prove strong subconvexity bounds for self-dual $\textrm{GL}(3)$ $L$-functions in the $t$-aspect and for $\textrm{GL}(3)\times\textrm{GL}(2)$ $L$-functions in the $\textrm{GL}(2)$-spectral aspect. The bounds are strong in the sense that they are the natural limit of the moment method pioneered by Xiaoqing Li, modulo current knowledge on estimates for the second moment of $\textrm{GL}(3)$ $L$-functions on the critical line.
