Ergodicity and mixing for locally monotone stochastic evolution equations

We establish general quantitative conditions for stochastic evolution equations with locally monotone drift and degenerate additive Wiener noise in variational formulation resulting in the existence of a unique invariant probability measure for the associated ergodic Markovian Feller semigroup. We prove improved moment estimates for the solutions and the $e$-property of the semigroup.
Furthermore, we provide quantitative upper bounds for the Markovian $\varepsilon$-mixing times.
Examples include the stochastic incompressible 2D Navier-Stokes equations, shear thickening stochastic power-law fluid equations, the stochastic heat equation, as well as, stochastic semilinear equations such as the 1D stochastic Burgers equation. Joint work with Gerardo Barrera (IST Lisbon).
