D- η - 珍视向量的功能的合适的 prequasi-invexity 被描绘借助于(弱) 将近集合的凸状和密度。在更弱的假设下面,某等价物为 D- 调节η - 合适的 prequasi-invexity 被导出。
The D-η-proper prequasi invexity of vector-valued functions is characterized by means of (weak) nearly convexity and density of sets. Under weaker assumptions, some equivalent conditions for D-η-proper prequasi-invexity are derived.
