Abstract

We study the Cauchy problem of nonhomogeneous micropolar fluid equations with zero density at infinity in the whole plane $ \mathbb{R}^2 $. We derive the global existence and uniqueness of strong solutions if the initial density decays not too slowly at infinity. Note that the initial data can be arbitrarily large and the initial density can contain vacuum states and even have compact support. Our method relies upon the delicate weighted energy estimates and the structural characteristics of the system under consideration.

Keywords:
