摘要
提出用一种新方法———构造法证明多元函数极限不存在 ,并得到了证明多元函数极限不存在的新条件。举例说明了利用构造法证明多元函数极限不存在比通常采用的观察法简单。
A new method is provided to prove the non existence of multivariable function limit by virtue of construction method. New conditions are also presented to prove the non existence of multivariable function limit , and then the method is illustrated with example that the new method is simpler than the commonly used observation method in proving the non existence of multivarible function limit.
