本文证明了在外部区域D中三维非齐次定常Oseen绕流的弱解的存在唯一性。我们主要使用局部化过程(参见Kozono and Sohr(1991))将我们以前的结果(参见Kracmar,Necasova,and Penel(2007,2008))与适当有界域中的经典结果联合收割机。我们研究了不可积右端的情形,其中f在(W-1,q(D))3中给出,对于q的某些值。
We establish the existence and uniqueness of a weak solution of the three-dimensional nonhomogeneous stationary Oseen flow around a rotating body in an exterior domain D. We mainly use the localization procedure (see Kozono and Sohr (1991)) to combine our previous results (see Kracmar, Necasova, and Penel (2007, 2008)) with classical results in an appropriate bounded domain. We study the case of a nonintegrable right-hand side, where f is given in (W ―1,q (D)) 3 for certain values of q.
