中文摘要:假定资产价格变化过程服从跳跃-扩散过程,那么基于它的欧式期权就满足一个偏积分-微分方程(PIDE),本文利用差分法来离散这个PIDE方程,用两种迭代方法得到方程的数值解:基于雅可比正则分裂法和预条件共轭梯度法. |

Numerical Solution of Assets Pricing Equation under Jump diffusion Model |
|
|
Abstract:The paper assume that the price process of the assets is a jump diffusion process, then, the value of European optaon satisfies a general partial integro differential equation(PIDE) under this assumption.The equation was discretized by difference formula.The result was obtained by two iterative methods:Jacobi regular splitting method and preconditioned conjugate gradient method. |
