基于Ornstein-Uhlenbeck过程,利用Fredholm型行列式和偏微分方程导出了某些二次布朗泛函的拉普拉斯变换的闭式表达式。作为特例,得到了二次布朗模型中的经典债券定价公式和新的债券定价公式。
We derive closed form expressions for the Laplace transform of certain quadratic Brownian functionals based on the Ornstein-Uhlenbeck process, using both Fredholm determinants and PDE arguments. Classical and new bond pricing formulas in quadratic Brownian models are obtained as particular cases.
