摘要
In this paper,we consider the reducibility of three-dimensional skew symmetric systems.We obtain a reducibility result if the base frequency is high-dimensional weak Liouvillean and the parameter is sufficiently small.The proof is based on a modified KAM theory for 3-dimensional skew symmetric systems.
