Decay characterization of weak solutions for the MHD micropolar equations on R2
We establish the characterization of decay rates of solutions to the 2D MHD micropolar system in terms of the decay character of the initial data. We also prove a faster decay rate for the micro-rotation. Moreover, we study the large time behavior of solutions by comparing them to solutions of the linear part. It is also shown that the difference between the micro-rotational field and its linear part decays faster.
