Global stability of large solutions to the 3-D compressible flow of liquid crystals
Pages: 887 – 908
The current paper is devoted to the investigation of the global-in-time stability of large solutions to the compressible liquid crystal equations in the whole space. Suppose that the density is bounded from above uniformly in time in the Höder space $C^\alpha$ with $\alpha$ sufficiently small and in $L^\infty$ space respectively. Then we prove two results: (1) Such kind of the solution will converge to its associated equilibrium with a rate which is the same as that for the heat equation. (2) Such kind of the solution is stable, which means any perturbed solution will remain close to the reference solution if initially they are close to each other. This implies that the set of the smooth and bounded solutions is open.
