“…The classical idea of approximating the Dirac distribution δ x by p ε has been used to calculate the chaotic decomposition of the local time in the case of the Brownian motion by Nualart and Vives [11] and for the fractional Brownian motion by Coutin et al [3] and Eddahbi et al [4]. Before stating precise results of this section, we prove some technical lemmas.…”

“…Section 2 is devoted to the presentation of the problem. In particular we review from [1] the chaotic decomposition of the local time L(t, x) as a functional of the (N, d)-fBm and its regularity in terms of SobolevWatanabe norms. In Section 3 we present a list of auxiliary lemmas.…”
