On the Stationary Solutions to 2D $g$-Navier-Stokes Equations

icon-email Dao Trong Quyet , Nguyen Viet Tuan

Abstract

We consider $g$-Navier-Stokes equations in a two-dimensional smooth bounded domain $\Omega$. First, we study the existence and exponential stability of a stationary solution under some certain conditions. Second, we prove that any unstable steady state can be stabilized by proportional controller with support in an open subset $\omega \subset {\Omega }$ such that $\Omega∖ \omega$ is sufficiently “small.”
