This article presents the definition of binary convex function,proves that the binary convex function in open and convex region must be continuous,popularizes Jensen s inequality and establishes the decision theorem of binary convex function.
该文给出了二元凸函数的定义,证明了开凸区域上的二元凸函数必连续,推广了Jensen不等式,建立了二元凸函数的判定定理。
3) convex and concave functions

1.
This article popularizes the single-dimensional random variable f≤Ef(ξ)(f(x) as convex and concave function into the multi-dimentional scope;therefore concludes a series of important inequalties esp,to convex and concave functions.
将一维随机变量的性质ｆ（Ｅξ）≤Ｅｆ（ξ），（ｆ（ｘ）为凸函数）推广到多维，以此统一推广了一类重要的不等式，对一个非凹凸函数给出了相关的不等式。
