Varadhan Estimates for rough differential equations driven by fractional Brownian motions
Fabrice Baudoin, Cheng Ouyang, Xuejing Zhang
In this work we study rough differential equations driven by a fractional Brownian motion with Hurst parameter H>1/4 and establish Varadhan's small time estimates for the density o…

Small-time kernel expansion for solutions of stochastic differential equations driven by fractional Brownian motions
Fabrice Baudoin, Cheng Ouyang
In this paper we show that under some assumptions, for a -dimensional fractional Brownian motion with Hurst parameter , the density of solution of stochastic differential…
