Conformal mapping and inverse conductivity problem with. Conformal mapping transforms a region in which the problem is posed to one in which the solution is easy to obtain. As our solutions involve only two independent variables, x and y , we first mention a basic assumption needed for the validity of the model. Conformal mapping is a short cut to the solution of the Laplace's equation, used in a limited group of engineering problems. The problem has to be 2D (two dimensional), i.e., the boundaries, boundary conditions and sources contain only two variables, x and y..
