The Enclosure Method and its Applications

The inverse conductivity problem is the problem of extracting several information about the coefficient γ in the uniformly elliptic equation ∇ · γu = 0 in a bounded domain Ω from the Cauchy data on ∂Ω of infinitely or finitely many solutions to the equation. We introduce a new method for attacking this problem and show its wide range of applicability. The metod is based on the new role of the exponentially growing solutions. Its applications to the Cauchy problem for an elliptic equation and the Dirichlet problem are also included.
