Abstract

We prove the local well-posedness for the barotropic compressible Navier-Stokes system on a moving domain, a motion of which is determined by a given vector field V{\bf V}, in a maximal LpLqL_p-L_q regularity framework. Under additional smallness assumptions on the data we show that our solution exists globally in time and satisfies a decay estimate. In particular, for the global well-posedness we don't require exponential decay or smallness of V{\bf V} in Lp(Lq)L_p(L_q). However, we require exponential decay and smallness of its derivatives.
