查询词典 derivative

Key words:the three dimensional contact problem with friction;nonlinearcomplementary;nonsmooth equations;generalized derivative;nonsmoothmethod;convergence analysis

给出了三维摩擦接触问题的一个非光滑混合不动点模型及算法，这种算法无须求导数，没有引进任何额外变量，并且可视为一种三维摩擦接触问题的迭代法，利用非光滑分析和不动点理论对算法做了分析，给出了算法的不动点理论背景及算法的理论分析，为模型解的存在性及算法收敛性提供分析依据，最后给出了相应的数值算例。

Furthermor, we consider their nondiferentiable situation, we define nonsmooth univex functions for Lipschitz functions by using Clarke generalized directional derivative and study nonsmooth multiobjective fractional programming with the new convexity. We establish generalized Karush-Kuhn-Tucker necessary and sufficient optimality condition and prove weak, strong and strict converse duality theorems for nonsmooth multiobjective fractional programming problems containing univex functions.

而且，本文利用Clarke广义方向导数针对Lipschitz函数在原来一致凸函数概念的基础上定义了不可微的一致凸函数，并利用这类新凸性，我们研究了非光滑多目标分式规划，获得了广义Karush-Kuhn-Tucher最优性条件；弱对偶定理、强对偶定理和严格逆对偶定理。

The generalized Law of Mean with unilateral derivative and its asymptotic features of the "centred dot" are studied.

本文研究了单侧导数的广义中值定理及其"中间点"的渐近性质，进而获得了更广泛的结果。

The geometric meaning of derivative.

导数的几何意义。

In spite of foreign currency option is a good evade risk tool, foreign currency option as a financial derivative itself gestate huge risk because of foreign currency produced as evading risk demand.

尽管外汇期权是一个非常好的避险工具，但是外汇期权组合作为规避风险需要而产生的金融衍生工具本身就孕育着极大的风险，因此对金融衍生工具的核心之一—外汇期权的风险进行研究是非常必要和适时的。
