Convergence rate of solutions toward stationary solutions to the isentropic micropolar fluid model in a half line

In this paper, we study the asymptotic behavior of solutions to initial boundary value problem for one-dimensional compressible isentropic micropolar fluid model in a half line \begin{document}$ \mathbb{R}_{+}: = (0, \infty). $\end{document} We mainly investigate unique existence, stability and convergence rates stationary outflow model. obtain global towards corresponding if perturbation belongs weighted Sobolev space. The proof is based on energy method by taking into account effect microrotational velocity viscous fluid.
