摘要：

We examine the inverse problem of determining the shape of some unknown portion of the boundary of a region Omega from measurements of the Cauchy data for solutions to the heat equation on Omega. By suitably linearizing the inverse problem we obtain uniqueness and continuous dependence results. We propose an algorithm for recovering estimates of the unknown portion of the surface and use the insight gained from a detailed analysis of the inverse problem to regularize the inversion. Several computational examples are presented.
