Abstract:We construct strong solutionsu, p/of the general nonhomogeneous Stokes equations -deltau + xdtrip=f inG, xdtri ·u=g inG, u=PHgr on gamma in an exterior domainG subRopfn (nges3) with boundary gamma of class C2. Our approach uses a localization technique: With the help of suitable cut-off functions and the solution of the divergence equation xdtri ·Ngr=g inG, Ngr = 0 on gamma, the exterior domain problem is reduced to the entire space problem and an interior problem.
