Abstract:In this talk, we present some results about for the Kordeweg-de Vries equation. We prove the analytic radius does not decay faster than $t^{-\frac{1}{4}} as time $t$ goes to infinity. For the high-order damped stochastic kdv equations with Brownian motion and Poisson jump processes, we prove the existence of the invariant measure, which is ergodic. This is a joint work with Ming Wang and Pengfei Xu.
