Rough path dynamics
WebJun 15, 2024 · The present work makes a first attempt to systematically connect the two fields of rough paths theory and random dynamical systems. In particular, we give sufficient conditions under which a random rough differential equation (0.4) d Y t = b ( Y t) d t + σ ( Y t) d X t ( ω); t ∈ [ 0, ∞) induces a random dynamical system.
