期权定价中的量子谐振子

Quantum harmonic oscillator in option pricing

Liviu-Adrian Cotfas, Nicolae Cotfas

摘要:

布莱克-斯科尔斯模型在执行价格与标的资产的当前价格相差不大的情况下,能够很好地预测期权的观察价格。对Black-Scholes方程中的系数作适当的修正,可以得到一些有用的推广。我们从数学的角度研究了一个与量子谐振子直接相关的推广。在所考虑的情况下,解决方案是一个系列的厄米-高斯函数的总和。利用有限振子和Harper函数得到了有限维形式。该简化模型保持了连续模型的基本特征,用有限和代替了级数和积分。

英文摘要:

The Black-Scholes model anticipates rather well the observed prices for options in the case of a strike price that is not too far from the current price of the underlying asset. Some useful extensions can be obtained by an adequate modification of the coefficients in the Black-Scholes equation. We investigate from a mathematical point of view an extension directly related to the quantum harmonic oscillator. In the considered case, the solution is the sum of a series involving the Hermite-Gauss functions. A finite-dimensional version is obtained by using a finite oscillator and the Harper functions. This simplified model keeps the essential characteristics of the continuous one and uses finite sums instead of series and integrals.
