Unstable manifolds for rough evolution equations

In this paper, we consider a class of evolution equations driven by finite-dimensional $\gamma$-Hölder rough paths, where $\gamma \in (1\mathrm{/}3,1\mathrm{/}2]$. We prove the global-in-time solutions of rough evolution equations(REEs) in a sutiable space, also obtain that the solutions generate random dynamical systems. Meanwhile, we derive the existence of local unstable manifolds for such equations by a properly discretized Lyapunov-Perron method.
