摘要: 对一类新的广义凸函数-预不变拟凸函数作了进一步研究。借助于η-不变凸集和函数的上图(E(f)={(x,α):x∈K,α∈R,f(x)≤α})得到了预不变拟凸函数的几个新的性质,然后还给出了预不变拟凸函数在数学规划问题中的两个重要应用,从而完善了对此类广义凸函数的研究。
关键词: 不变凸集, 预不变拟凸函数, 应用
Abstract: A new class of important generalized convex functions-prequasi-invex function is further discussed.To improve research on the generalized convex function,some new characteristics of the prequasi-invex function are figured out by means of the cographical set of function (E(f)={(x,α):x∈K,α∈R,f(x)≤α}) and η-invex set,and its two applications in the mathematical programming problem are proposed.So the study of this type generalized convex function becomes further now.
Key words: invex set, prequasi-invex functions, application
