Long-time behavior of solution to the compressible micropolar fluids with external force

In this paper, we are concerned with the long time behavior for the compressible micropolar fluids with a potential external force in R3. Under the smallness assumption on both the initial perturbation and the external force in some Sobolev spaces, the optimal convergence rates of the solution and its first order derivative in L2-norm are obtained when the initial perturbation is bounded in L1.
