The compressible Euler system with damping in hybrid Besov spaces: global well-posedness and relaxation limit
Timothée Crin-Barat, Zihao Song
We investigate the global well-posedness of the compressible Euler system with damping in Rd (d\geq1) and its relaxation limit toward the porous medium equation. In [12], the first…

Global well-posedness for the 3D compressible Navier-Stokes equations in optimal Besov space
Zihua Guo, Zihao Song, Minghua Yang
We consider the Cauchy problem to the 3D barotropic compressible Navier-Stokes equation. We prove global well-posedness, assuming that the initial data has small norm…
