Abstract:
Solutions of the initial boundary value problem for Navier–Stokes
equations are approximated by solutions of the initial
boundary value problem
\begin{gather*}
\partial_t u(t)+u_k(t)\partial_ku(t)-\nu\Delta u(t)-\frac1\varepsilon\nabla\mathrm{div}\,u(t)+\frac12u(t)\mathrm{div}\,u(t)=f(t),\\
u(0)=u_0\text{ in }\Omega;\quad u(t)=0\text{ on }\partial\Omega.
\end{gather*}
We study proximity of solutions of these problems in suitable
norms and also proximity of their minimal global $B$-attractors.
