关于多元函数的凹凸性
The Study of Convex and Concave Characteristics of Melti-element Function
【摘要】 将一元函数的凹凸性概念推广到多元函数,给出了多元函数为凸函数或严格凸函数的若干充要条件.
【Abstract】 The concept of convex and concave characteristics in one-element function was extended to multi-element function.Several causal and necessary conditions were provided,through which multi-element function will be convex function or will strictly be convex function.
