本文研究Hurst参数H∈(0,1)的分式布朗运动的加权局部时.利用多重Wiener-Ito积分,得到了分式布朗运动的加权局部时的展开式,推广了布朗运动的加权局部时问题.
In this paper, we study weighted local time of fractional Brownian motion with arbitrary Hurst parameter H ∈ (0, 1) via white noise approach, which means to regard it as a Hida distribution. Expansion of weighted local time for fractional Brownian motion is obtained in terms of multiple Wiener-Ito integrals. The problem of weighted local time of Brownian motion is generalized.
