摘 要: 讨论了高维拟线性非自治系统x=A(t,x)x+g(t,x)周期解的存在性问题.得到了判别周期解存在的充分条件.推广了已有主要结果. The existence of periodic g solution of a class of high order quasilinear nonautonomic periodic system =A(t,x)x+g(t,x) is discussed. A simple criterion of the existence of periodic solutions is obtained, which extends the main results before.
