本文给出扩散半群微分的Bismut-Elworthy-Li公式的高阶离散格式。在Wiener空间上通过分部积分构造了一种带Malliavin权的弱近似型算法,并利用MonteCarlo方法有效地实现了该算法。我们给出了一个尖锐的误差估计的Malliavin演算的基础上的离散化。对金融期权Delta的数值敏感性分析表明了该方案的有效性。
This paper shows a higher order discretization scheme for the Bismut--Elworthy--Li formula, the differentiation of diffusion semigroups. A weak approximation type algorithm with Malliavin weights is constructed through the integration by parts on Wiener space and is efficiently implemented by a Monte Carlo method. We give a sharp error estimate for the discretization based on Malliavin calculus. Numerical sensitivity analysis for the option delta in finance shows the validity of the proposed scheme.
