摘要:期权定价理论是现代金融理论最为重要的成果之一,期权定价方程可以用来制定各种金融衍生产品的价格,是各种金融衍生产品估价的有效工具, 但求其解析解仍是科研难题。本文首先将整数阶偏微分方程推广到分数阶,然后求解。 首先我们引入了分数阶微分方程的定义及其运算方法。主要利用了Liouville Riemann 分数阶积分和Caputo 公式的转化方程来求解 阶导数。我们计算到四节近似解析解,将 4 u 结果代入原方程中,并取相应的利率和波动率的值就可以进行误差分析,分别取 )。利用 a Mathematic 软件做出图像,我们可以看出误差范围在 210 。由此可以说明分数阶微分方程具有较高的准确度。通过软件的误差分析可以证明该方法的误差较小, 但是仍需要实际的期权数据来进行验证, 即该方法是否对于欧式期权及各种奇异期权都较为准确地预测出期权价格。并且本毕业论文由于时间关系未能迭代出四阶以上的结果,因此仍需要后期简化计算过程,或者找到新的算法思路进行迭代运算。因此这两点将是分数阶求解 Scholes Black 方程后期需要做的工作。20005 关键字:分数阶微分方程 Caputo 公式 Scholes - Black 方程 误差分析 The application of fractional order differential equation on financial Abstract: Option pricing theory is one of the most important achievements of modern finance theory. option pricing equation can be used to set prices of various financial derivative products and it is an effective tool for a variety of financial derivatives valuation. it is still a research problem for solving its analytical solution. In this paper, we put the integer order partial differential equations generalized to differential equations and then solve it. Firstly, the arithmetic of fractional differential equations is used to calculate B-S equation. The main calculation formulas are Liouville Riemann fractional integral and Caputo fractional derivative. Because this process leads to a large amount of calculation and time-consuming, we can get the first 4 terms. Then the plots of residual analysis is made by using fixed rate and volatility along with different .The results show that the error range is in 2 , which can prove the fractional differential equation has high accurate. This method has less error through residual analysis, but still need be verified by real option data. Whether this method has better results on European style options and other exotic options. Due to time constrains, the fifth order has not been iterated out, so we need new ways to simplify the computational process.
