摘要
在已有凸函数文献的基础上,讨论了凸函数的13种不同定义,并对各种定义形式之间的等价性进行了完整的分析和证明,对凸函数理论及已有文献中的相应结论进行了进一步的改进.
Based on the known results, the thirteen kinds of definitions were summarized about convex function and the equivalence of them was discussed completely. Further improvement is made on convex function theory and con- clusions in literature.
