在本文中,fCR 3表示具有一致C2-边界的一般三维区域,其中主要的兴趣集中在具有非紧边界的区域上。众所周知,Lq-空间中Stokes方程的标准方法,l< q< oc,不能推广到Lq,q ~ 7 ~ 2中的一般无界区域;关于Helmholtz分解的反例,见[7]和[24]。然而,为了建立任意域的斯托克斯方程的完整且类似的理论,我们用以下公式替换空间Lq(f~)
Throughout this paper, f~ _CR 3 means a general 3-dimensional domain with uniform C2-boundary 0f~# Z, where the main interest is focussed on domains with noncompact boundary Oft. As is well known, the standard approach to the Stokes equations in L q-spaces, l< q< oc, cannot be extended to general unbounded domains in Lq, q7~ 2; for counterexamples concerning the Helmholtz decomposition, see [7] and [24]. However, to develop a complete and analogous theory of the Stokes equations for arbitrary domains, we replace the space Lq (f~) by
