利用Dini方向导数讨论向量不变 h- 伪线性函数； 通过半序方法给出若干不可微且不变的伪线性方程解集的特性.
The vector invariant pseudolinear functions was introduced by using the means of Dini directional derivatives. Some properties of vector pseudolinearity functions were discussed by using the concept of semi-order, including some characterizations of the solution set of a nonconvex and nondifferentiable, but invariant, pseudolinear program.
