On the other hand,the ConstantRank Theorem is a refined statement of convexity. It has become a powerful tool in thestudy of the geometric properties of solutions of partial differential equations.
同时,常秩定理是处理关于凸性问题的一个强有力工具,它在偏微分方程解的几何性质及微分几何中的应用有着深刻意义。
Once the convexity bias adjustment is completed, the hedged portfolio generates zero excess return.
如果凸度偏移调整是完全的,套期保值组合将产生零超额回报。
There is no certain and positive relationship between convexity and bond extra return and liquidity and investor behavior make great impact on the role of immunization strategies.
研究还显示,凸性与债券超额回报之间可能不存在必然的联系,市场流动性和投资者行为对免疫策略的效果产生重要的影响。
