Local Times of Some Processes Associated with Fractional Bessel Processes
摘要
Abstract
Let BH=(B1H,B2H,… ,BdH) be a d-dimensional fractional Brownian motion with Hurst parameter 0<H<1 and let RH=√(B1H)2+(B2H)2+…+(BdH)2 be the fractional Bessel process. In this paper, we consider the process XH given by XH(t)=d∑j=1∫t0BjH(s)/RH(s)dBjH(s) and obtain the local time of XH and Tanaka formula. As a corollary, we get a relationship between the weighted local time of fractional Brownian motion and the local time of the process XH for d=1.关键词
