Global low-energy weak solutions for compressible magneto-micropolar fluids with discontinuous initial data in R^3

Abstract

This article concerns the weak solutions of a 3D Cauchy problem of compressible magneto-micropolar fluids with discontinuous initial data. Under the assumption that the initial data are of small energy and the initial density is positive and essentially bounded, we establish the existence of weak solutions that are global-in-time. Moreover, we obtain the large-time behavior of such solutions. For moreinformation see https://ejde.math.txstate.edu/Volumes/2023/86/abstr.html
