Global strong solvability of the Navier-Stokes equations in exterior domains for rough initial data in critical spaces

Abstract

It is well known that the Navier-Stokes equations have unique global strong solutions for standard domains when initial data are small in $L^n_\sigma$. Global well-posedness has been extended to rough initial data in larger critical spaces. This paper explores the global strong solvability of the smooth exterior domain problem for initial data that is small in some critical spaces larger than $L^n_\sigma$
