Dr. Tommaso Rosati (University of Warwick): Lower bounds to Lyapunov exponents for stochastic PDEs, Kolloquium Partial Differential Equations

Inspired by problems from fluid dynamics, we introduce an approach to obtain lower bounds for Lyapunov exponents of stochastic PDEs. Our proof relies on the introduction of a novel Lyapunov functional for the projective process associated to the equation, based on the study of dynamics of the energy median and on a notion of non-degeneracy of the noise that leads to high-frequency stochastic instability. Joint work with Martin Hairer.
