连续凸函数的判据及几何特征
The Criterion and the Geometric Character for the Continuous Convex Function
【摘要】 从凸函数定义出发研究了连续函数与凸函数的关系,给出了连续凸函数的几个判定条件,并刻划它们的几何特征.
【Abstract】 From the definitions of the convex function,the relations of continuous function and convex function is discussed in this paper.Some criterions for the continuous convex function are given,and the geometric characters of their is scored.
