Amplitude equations for SPDEs with quadratic nonlinearities forced by additive and multiplicative noise
arXiv:2112.06229
Abstract
This article deals with stochastic partial differential equations with quadratic nonlinearities perturbed by small additive and multiplicative noise. We present the approximate solution of the original equation via the amplitude equation and give the rigorous error analysis. For illustration, we apply our main theorems to stochastic Burger's equation.
