Explicit subconvexity for $\mathrm{GL}_2$

Number Theory 2022-06-22 v5

Abstract

We make the subconvex exponent for GL2\mathrm{GL}_2 cuspidal representation in the work of Michel \& Venkatesh explicit. The result depends on an effective dependence on the `fixed' GL2\mathrm{GL}_2 representation in our former work on the subconvex bounds for twists by Hecke characters, which in turn depends on the L4\mathrm{L}^4-norm of the test function.
