Firstly, E-convex sets are defined in real linear Spaces and some its properties are discussed.
首先在实线性空间中定义了E -凸集并讨论了E -凸集的基本性质。
In this paper, with the aid of idea of defining those sets and functions, the definitions of E -convex cone, pseudo-quasi- E -convex functions, E -direction derivative are discussed.
借助于这些集合和函数的定义思想，本文定义了E -凸锥、伪拟E -凸函数、E -凸函数方向导数等几种更广义的概念。
