We simplify the proof of subconvexity bounds for $L(\\frac{1]{2}, f \\otimes \\chi)$ when $f$ is a primitive holomorphic cusp form of level $P$ and $\\chi$ is a primitive Dirichlet character modulo $M$. These bounds are attained through an unamplified second moment method using a modified version of the delta method due to R. Munshi. The technique is similar to that used by Duke-Friedlander-Iwaniec save for the modification of the delta method."},"keywords":[["Special values of L-functions"],["Rankin-Selberg convolution"],["subconvexity"],["\u03b4-method 2010 Mathematics Subject Classification 11F11"],["11F67"],["11L05"],"[ MATH ] Mathematics [math]","[ MATH.MATH-NT ] Mathematics [math]\/Number Theory [math.NT]"]}
