三、摘要
We prove an abstract infinite dimensional KAM theorem, which could be applied to prove the existence and linear stability of small-amplitude quasi-periodic solutions for one dimensional forced Kirchhoff equations with Dirichlet boundary conditions

whereMis a real Fourier multiplier,g(wt,x)is real analytic and odd inxwith forced Diophantine frequencies w,ois a small parameter.The proof is based on an improved Kuksin lemma and the off-diagonal decay property of the forcing term.This is a joint work with Yin Chen.
