Title：Response solutions for reversible harmonic oscillators with finite smooth

Abstract：The KAM method is a useful way to prove the existence of quasi-periodic solutions for some ordinary differential equations.  In this talk, we will discuss the response solutions for some reversible harmonic oscillators with finite smooth forcing. When the forcing term is analytic, this problem is widely investigated. However, there are few results about the finite smooth case. The proof is based on the KAM theory for elliptic lower dimensional reversible systems with finite smooth.
