Non-classical large deviations for a noisy system with non-isolated attractors
Non-classical large deviations for a noisy system with non-isolated attractors
We study the large deviations of a simple noise-perturbed dynamical system having continuous sets of steady states, which mimick those found in some partial differential equations related, for example, to turbulence problems. The system is a two-dimensional nonlinear Langevin equation involving a dissipative, non-potential force, which has the essential effect …
