Abstract
In this paper, we consider Ornstein-Uhlenbeck process d X t H = − X t H d t + v d S t H , X 0 H = x, driven by a subfractional Brownian motion S H . We prove that the subfractional Ornstein-Uhlenbeck process X H is local nondeterministic and give some properties of this process. As an application, assume d ≥ 2 , we prove that the intersection local time of two independent, d − dimensional subfractional Ornstein-Uhlenbeck process, X H and $\tilde{ X}^H$ , exists in L 2 if and only if Hd< 2 .
