Bounds for twisted symmetric square $L$-functions - III

Abstract

Let $f$ be a newform, and let $\chi$ be a primitive character of conductor $q^{\ell }$. Assume that $q$ is an odd prime. In this paper we prove the subconvex bound $$ L(\t1/2,\Sym f\otimesχ)\ll_{f,q,\varepsilon} q^{3\ell(1/4-1/36+\varepsilon)} $$ for any $\epsilon >0$. This can be compared with the recently established $t$-aspect subconvexity of the symmetric square $L$-functions.
