摘要
In this paper we study a singular stochastic differential equation driven by an additive fractional Brownian motion with Hurst parameter H > 1/2. Under some assumptions on the drift, we show that there is a unique solution, which has moments of all orders. We also apply the techniques of Malliavin calculus to prove that the solution has an absolutely continuous law at any time t > 0. (C) 2008 Elsevier B.V. All rights reserved.
