Abstract

Let gg be a fixed holomorphic cusp form of arbitrary level and nebentypus. Let χ\chi be a primitive character of prime-power modulus q=pγq = p^{\gamma}. In this paper, we prove the following hybrid Weyl-type subconvexity bound \begin{align*} L (1/2 + it, g \otimes \chi) \ll_{g, p, \varepsilon} ( (1+|t|) q )^{1/3+ \varepsilon} \end{align*} for any ε>0\varepsilon > 0.
