1) axiom of convexity
凸性公理
2) ideal convexity
理想凸性
1.
The ordinary convexity,geometrical convexity,logarithmical convexity and the exponential convexity are mentioned in the first two sections;the ideal convexity,integral convexity and the β-convextiy are presented in the central three sections;for the more generalized convexties are briefly introduced in the last section.
本文第一节简述通常凸性概念及其在不等式理论方面的几个简单应用,第二节简介几何凸性、对数凸性、指数凸性及其与通常凸性之间的相互关系;第三节介绍集合与函数的理想凸性;第四节简介由笔者首创的积分凸性及其进展。
3) concavity theory
凸性引理
4) the concavity method
凸性原理
5) protrusion theorems
凸性定理
6) rational convexity
有理凸性
补充资料：凸性
凸性 Convexity
定义：
衡量债券自卫能力的指标。当凸性为正，债券会因利率上扬而使平均存续期间(duration)和跌价幅度均变小；而若利率下跌，平均存续期间及涨价的幅度皆会放大。
