Limit behavior of the Rosenblatt Ornstein-Uhlenbeck process with respect to the Hurst index

We study the convergence in distribution, as H → 1 2 and as H → 1, of the integral R f (u)dZ H (u), where Z H is a Rosenblatt process with self-similarity index H ∈ 1 2 , 1 and f is a suitable deterministic function. We focus our analysis on the case of the Rosenblatt Ornstein-Uhlenbeck process, which is the solution of the Langevin equation driven by the Rosenblatt process.
