摘要
指出了L′Hospital法则对一般的复值函数并不成立 ,并给出了其成立的一些充分条件 。
This paper points out L′Hospital law for general complex valued function does not hold, then gives some sufficent conditions for its holding and finally, by using the result,proves a fundamental theorem used in the study of singular differential equations. [WT5HZ]
