Stochastic extrema as stationary phases of characteristic functions

S. Nikitin

摘要:

本文研究随机过程的特征函数的半经典渐近性。主要技术工具是固定相法。随机过程的极值范围由特征函数的复对数的极限值定义。本文还概述了一种计算随机极值的数值方法。

英文摘要:

The paper is dealing with semi-classical asymptotics of a characteristic function for a stochastic process. The main technical tool is provided by the stationary phase method. The extremal range for a stochastic process is defined by limit values of the complex logarithm of the characteristic function. The paper also outlines a numerical method for calculating stochastic extrema.
