摘要
将凸函数次微分的概念稍加改变,引入一般函数次微分并借助凸化方法得到函数的凸扩张存在的充分必要条件,借助凸分析原理对优化问题展开了研究.
In the paper, we change the notion of subdifferential of convex functions new subdifferential of general functions and obtain sufficient and necessary conditions of slightly, introduce a existence of convex extensions by convexification, we can then study optimization problems by convex analysis.
