Local times of stochastic differential equations driven by fractional Brownian motions
Shuwen Lou, Cheng Ouyang · 2016-02-24 · via math.PR updates on arXiv.org

In this paper, we study the existence and (Hölder) regularity of local times of stochastic differential equations driven by fractional Brownian motions. In particular, we show that in one dimension and in the rough case H<1/2, the Hölder exponent (in t) of the local time is 1-H, where H is the Hurst parameter of the driving fractional Brownian motion.
