Abstract: In this paper we prove the existence and uniqueness of time global mild solutions to the Navier-Stokes-Oseen equations, which describes dynamics of incompressible viscous fluid flows passing a translating and rotating obstacle, in the solenoidal Lorentz space $L_{\sigma, {\rm{w}}}^3$. Besides, boundedness and polynomial stability of these solutions are also shown.

Key words: Time global mild solutions, Navier-Stokes-Oseen equations, Oseen operator, rotating and translating obstacle
