报告摘要:This talk is concerned with an inverse boundary value problem for the Stokes equation with discontinuous viscosity coefficients in a two- or three-dimensional bounded domain. We demonstrate that the shape and location of the inclusion can be uniquely recovered by the local Dirichlet-to-Neumann map defined on an arbitrary small open subset of the boundary. We then show that the discontinuous viscosity coefficient can be uniquely recovered by the same boundary measurement, if the viscosity coefficient satisfies an a priori assumption on the boundary of the inclusion.
