C^∞偶函数的Whitney引理

Whitney＇s Lemma of C^∞ Even Functions

将奇点理论中的Whitney引理从关于微分芽的局部情形推广到了定义在Rn×R上的C∞函数的情形,扩大了该引理的应用范围.

In this paper, Whitneyrs Lemma in the singularity theory is generalized from a local result about differentiable germs to C^∞ functions defined on R^n× R, which will extend the application of this Lemma.
