Our results concern a formal solution of the geometrically inverse problem for localisation and reconstruction of the form of absorbing domains. Here, we restrict our analysis to the one- and two-dimensional cases. We show that the last case can be studied by the conformal mapping technique. To illustrate this, we scrutinize the constant boundary conditions and analyze a numeric example.</p></abstract><kwd-group xml:lang="en"><kwd>Laplacian transport</kwd><kwd>Dirichlet-to-Neumann operators</kwd><kwd>Conformal mapping</kwd></kwd-group><funding-group><funding-statement xml:lang="en">During his visit of Indiana University- Purdue University Indianapolis, V.A.Z. benefited of numerous useful suggestions and comments concerning the present paper from discussions with Pavel Bleher.
