Convex function - Wikipedia
The concept of strong convexity extends and parametrizes the notion of strict convexity. Intuitively, a strongly-convex function is a function that grows as fast as a quadratic function. [11]
Convexity in Bonds: Definition and Examples - Investopedia
Jul 15, 2025 · Convexity is the curvature in the relationship between bond prices and bond yields. Convexity demonstrates how the duration of a bond changes as the interest rate changes.

函数凸性 | 中文数学 Wiki | Fandom
函数的凸性(convexity)是除了函数单调性之外的又一个重要性质,这里我们以一元实函数为例研究。 注意在不同的教材中定义凸函数可能完全相反。
Basically, our various notions of convexity have implications about the nature of minima. It should not be surprising that the stronger conditions tell us more about the minima.
