We considered the problem of extracting several information about the coefficient in a uniformly elliptic equation in a bounded domain from the Cauchy data on the boundary of the domain of infinitely many solutions of the equation. We proposed three mathematical methods for the purpose. These are called the probe method, the enclosure method and the slice method. Applications to the Cauchy problem, the inverse scattering problem and the inverse conductivity problem in an unbounded domain are given.

我们考虑了从方程无穷多个解域边界上的柯西数据中提取有界域中均匀椭圆方程系数的多个信息的问题。为此我们提出了三种数学方法。这些方法称为探测法、封闭法和切片法。给出了无界域中柯西问题、逆散射问题和逆电导率问题的应用。
