集值优化问题ε－强有效解的最优性条件
Optimality conditions of ε－strongly efficient solutions for set-valued optimization problem

引入集值映射ε－强有效次梯度和ε－强有效次微分的概念. 在一定条件下得到该次微分的存在性定理，讨论该次微分的一些性质. 作为应用，对于一类特殊的参数扰动优化问题，研究其在ε－强有效意义下的稳定性
The concepts of ε－strongly efficient subgradient and ε－strongly efficient subdifferential for s set-valued map are introduced. Under some certain conditions，the existence theorem for ε－strongly efficient subdifferential is proposed，and some properties of this subdifferential are discussed. As an application，the stability problem for a kind of particular perturb optimization problem is considered in the sense of strongly efficiency
