将考虑Rn(n≥2)中有界Lipschitz区域上,分片常系数复合材料折射问题的反问题.我们将利用层位势技巧,通过单测量数据——非零Neumann边值来确定内部材料传导系数的唯一性.
Let Ω be a bounded Lipschitz domain in Rn,n≥2.Inverse problem of recovering piecewise constant conductivity was considered for refraction from composite materials.The layer potential technique was used to determine uniquely the unknown conductivity k in a fixed sub-domain of Ω,from one measurement corresponding to arbitrary nonzero Neumann data.
