本文提出集值映射的ε-超次梯度概念.在某种假设下,利用凸集分离定理得到ε-超次梯度的存在性定理.给出一个具体例子解释主要结果.
The concept of ε-super subgradient for a set-valued map is introduced. Under certain hypothesis, by applying separation theorem for convex sets, the existence theorem for an ε-super subgradient is obtained. An example is given to illustrate the main result.
