题目：A new method for solving some first passage time problems by Laguerre series expansion
报告人：张志民 教授 重庆大学
摘要：
We propose for the first time an explicit closed-form Laguerre series expansion formula for the first passage time density function of a general jump diffusion. In contrast to existing methods in the literature based on numerical Laplace transform inversion, the proposed formula enjoys several advantages: it is in analytical closed-form, simple to implement, and converge quickly. Two methods are proposed to compute the Laguerre coefficients, where the first method is based on the fluid embedding technique, and the second method relies on potential densities. Various numerical examples are presented to show effectiveness of our method.
