In this paper, the existence and chaos decomposition
of local time of fractional Brownian motion are studied within the canonical
framework of white noise analysis. We prove that the local time of -dimensional
fractional Brownian motion with 1-parameter is a Hida distribution through white
noise approach. Under some conditions, it exists in . Moreover, the
Wiener-Ito chaos decomposition of it is also given in terms of Hermite
polynomials. Finally, similar results of -dimensional fractional Brownian
motion with -parameter are also obtained. We popularize some results in
Bakun (2000) for the case of Brownian motion.
