M. A. Dagnaw, C. Fresneda-Portillo

摘要:

利用显式参数(Levi函数)势方法,导出了可压缩Stokes系统的两个等价于狄利克雷问题的边界域积分方程组.的BDIE给出的表面和体积流体动力学势。我们研究了这些积分势算子的映射性质,并用它们证明了考虑单层和超奇异流体动力表面势的非平凡核所得到的两个BDIE系统解的存在性和唯一性。

英文摘要:

We derive two systems of boundary-domain integral equations (BDIEs) equivalent to the Dirichlet problem for the compressible Stokes system using the potential method with an explicit parametrix (Levi function). The BDIEs are given in terms of surface and volume hydrodynamic potentials. We study the mapping properties of these integral potential operators and used them to prove existence and uniqueness of solution of the two systems of BDIEs obtained taking into account the non-trivial kernels of the single layer and hypersingular hydrodynamic surface potentials.
