摘要 研究了G-预不变凸函数的一些重要性质,建立了G-预不变凸函数的一个等价条件,并利用该等价条件给出了二次连续可微的G-预不变凸函数的一个充要条件.此外,也建立了可微的G-预不变凸函数的一个充要条件. Some important characterizations about G-preinvex functions are obtained.Firstly,an equivalent condition about G-preinvex functions is established.Furthermore,a necessary and sufficient condition of a twice continuously differentiable G-preinvex function is provided by making use of the equivalent condition.At last,a necessary and sufficient condition is established about differentiable G-preinvex functions.
