Minimax Theorems for Extended Real-Valued Abstract Convex–Concave Functions
研究了扩展实值抽象凸凹函数极小极大等式成立的充要条件，并应用于扩展实值凸凹函数，为优化理论提供基础。
In this paper, we provide sufficient and necessary conditions for the minimax equality for extended real-valued abstract convex–concave functions. As an application, we get sufficient and necessary conditions for the minimax equality for extended real-valued convex–concave functions.
