Normal Form for Families of Hamiltonian Systems
《Acta Mathematica Sinica,English Series》2007年第7期1199-1216,共18页Zhi Guo WANG

We consider perturbations of integrable Hamiltonian systems in the neighborhood of normally parabolic invariant tori. Using the techniques of KAM-theory we prove that there exists a canonical transformation that puts ...

An Improved Result for Positive Measure Reducibility of Quasi-periodic Linear Systems被引量:2
《Acta Mathematica Sinica,English Series》2006年第1期77-86,共10页Hai Long HE Jian Gong YOU 
The work is supported by the National Natural Science Foundation of China (19925107) and the Special Funds for Major State Basic Research Projects (973 Projects)
In this paper, by the KAM method, under weaker small denominator conditions and nondegeneracy conditions, we prove a positive measure reducibility for quasi-periodic linear systems close to constant: X = (A(λ) ...
