二元函数的局部收敛性

The Local Convergence of two - Variable function

在减弱“一致收敛”的情况下给出了x→a时f(x,y)的极限函数的连续性、可积性、可微性以及极限号与积分号、微分号交换次序的几个定理。

In this paper, in the condition of weakening 'uniform convergence' , the authors give some propositions on about the limitative function,s continuity, integrability, differentiability, and some theorems for limit to exchange symbol order with integration or differentiation.
