摘要:

 文中考虑一类最多可以指数地有理逼近的无理数,并指出它们自然地存在于偏微分方程
解析理论及动力系统中.

关键词: 丢番图逼近, Gevrey类, 亚椭圆性, Liapunov稳定性, 几乎周期运动

Abstract:

IN THIS paper,we consider a class of irrational rumber which can be  approximated by rational number at most exponental order,Applications are given in partial differential equation and dynamical systems.

Key words:  Diophantineapproximation, Gevreyclass, Hypoellipticity, Liapunovstability, Almostperiodicmotion.
