具有两对 Cauchy 数据的反导电率问题的 Lipschitz 稳定性

Lipschitz stability of an inverse conductivity problem with two Cauchy data pairs

Martin Hanke

AI总结:

本文证明了具有两对 Cauchy 数据的反导电率问题中线性化前向映射的单射性,推导出非线性反问题解的 Lipschitz 稳定性,并指出绝缘包含物仅需单对数据即可。

摘要:

1996年 Seo 证明了在平面均匀物体表面测量的两对适当的电流和电压数据,足以确定具有已知偏离导电率的导电多边形包含物。在此我们证明相应的线性化前向映射是单射的,并由此推导出原始非线性反问题解的 Lipschitz 稳定性。我们还处理了绝缘多边形包含物的情况,在这种情况下,单对 Cauchy 数据已足以实现相同目的。

英文摘要:

In 1996 Seo proved that two appropriate pairs of current and voltage data measured on the surface of a planar homogeneous object are sufficient to determine a conductive polygonal inclusion with known deviating conductivity. Here we show that the corresponding linearized forward map is injective, and from this we deduce Lipschitz stability of the solution of the original nonlinear inverse problem. We also treat the case of an insulating polygonal inclusion, in which case a single pair of Cauchy data is already sufficient for the same purpose.
