摘要：Different from Brownian motion, fractional Brownian motion (fBm) is neither Markovian nor a semi-martingale. Little seems to be known about the long-time behavior of systems with an fBm. In this respect, we shall report two recent results. First, we establish the existence of random attractors for SPDEs driven by rough path with H?lder index in (1/3, 1/2] by combining rough paths theory and stopping times analysis in a scale of interpolation spaces. Second, we analyze the Lu-Schmalfu? conjecture on the existence of stable manifolds for SPDEs with nonlinear multiplicative fractional noise. To this aim, we construct a function space in which the discretized Lyapunov-Perron-type operator has a unique fixed point. The two papers are written in collaboration with Qigui Yang, Xiaofang Lin and Alexandra Neam?u.
