Subconvexity bound for GL(3) ×GL(2)L-functions : Hybrid level aspect

Let F be a GL(3) Hecke-Maass cusp form of prime level P 1 and let f be a GL(2) Hecke-Maass cuspform of prime level P 2 .We will prove a subconvex bound for the GL(3) × GL(2) Rankin-Selberg L-function L(s, F × f ) in the level aspect for certain ranges
