在边界邻域的电导率精确已知的情况下,我们用局部数据证明了电阻抗断层扫描的最佳稳定性估计。这里的主要新颖之处在于,我们提供了一种相当通用的方法,当在两个边界之间的层中系数已知时,该方法能够从更大域上的局部狄利克雷到诺伊曼映射获得全局狄利克雷到诺伊曼映射的 H'older 依赖关系。
We prove an optimal stability estimate for Electrical Impedance Tomography with local data, in the case when the conductivity is precisely known on a neighborhood of the boundary. The main novelty here is that we provide a rather general method which enables to obtain the H"older dependence of a global Dirichlet to Neumann map from a local one on a larger domain when, in the layer between the two boundaries, the coefficient is known.
