严格凸函数的充要条件

Sufficient and Necessary Conditions of Strictly Convex Functions

严格凸性是函数的各种凸性中最强的一种，严格凸函数有着许多其他广义凸函数所没有的独特性质。应用研究广义凸函数的方法，对Ｒ￣ｎ中的严格凸函数作了进一步研究，给出了严格凸函数的一些性质。

The strict convexity is one of the strongest generalized convexities in all functions. The strictly convex functions in Rn-space, having many features different from other ones, is discussed by studying generalized convex functions and its some characteristics is given.
