摘要
利用BEN-TAL广义代数运算对强预不变凸函数和(h,φ)-η-预不变凸函数进行推广,定义了一类新的广义(h,φ)-凸函数-ρ-(h,φ)-弱预不变凸函数,给出并证明了它的一些性质。
As a generalization of convex functions, strongly preinvex functions and ( h, φ) - η - preinvex functions are two classes of very important functions and which are quite widely applied to mathematical programming. In the paper, through utilizing Ben - Tal generalized algebraic operations to generalize strongly preinvex functions and ( h, φ) - η- preinvex functions, a new class of generalized ( h ,φ) - convex functions,ρ - ( h ,φ) - weakly preinvex function, is defined and some properties of it are given and proven too.
