摘要
引入了严格r-预不变凸函数的概念,并证明了严格r-预不变凸函数与r-预不变凸函数有关的一个充分条件.同时,讨论得到了严格r-预不变凸性和半严格r-预不变凸性的等价条件.
In this paper, we introduce a new conception of the strictly r-preinvex function and prove some related properties. These properties include a sufficient condition in terms of strict r-preinvexity and r-preinvexity. A new equivalent condition between strict r-preinvexity and semistrict r-preinvexity are also presented
