Lagrangian coherent structures are structures which separate dynamically distinct regions in time-varying systems such as turbulent flows in fluid mechanics. They can be defined in terms of finite-time Lyapunov exponents based on a frame-independent description of the system in terms of Lagrangian mechanics.[1]
