多频常微分方程的几何奇异扰动理论

perturbation. Acta Math Sci,to appear Geometric Singular Perturbation Theory for Ordinary Differential Equations with Multifrequency

在该文中，作者把常微分方程的几何奇异扰动理论推广到具多个频率的系统，同时给出了一个例子来说明主要理论．

In this paper,we generalize the geometric singular perturbation theory of ordinary differential equations to multifrenquency systems. An example is given to explain the main theory.
