摘要
本文讨论多元函数方向极限、重极限与累次极限三者之间的相互关系.给出了重极限与累次极限的五种关系;给出了方向极限、重极限与累次极限的三种关系.并对相应情形进行了讨论.
We discuss the relationship among the three limits.Five relations between the multivariable limit and the iterated limit are given,and three relations among the directional limit,the multivariable limit,and the iterated limit are given.Examples are used to discuss the corresponding cases.
