Large deviations for stochastic Kuramoto–Sivashinsky equation with multiplicative noise

open access: yesNonlinear Analysis, 2021
The Kuramoto–Sivashinsky equation is a nonlinear parabolic partial differential equation, which describes the instability and turbulence of waves in chemical reactions and laminar flames. The aim of this work is to prove the large deviation principle for
