WebJul 25, 2024 · The asymptotic log-Harnack inequality is proved for Leray- α model with degenerate type noise using the asymptotic coupling method. In particular, we don’t impose any lower bound assumption for the viscosity constant. As applications, we also derive ergodicity and further asymptotic properties for stochastic 3D Leray- α model.
