Jukka-Pekka Humaloja - Speaker

Consider an electrical potential u satisfying Laplace's equation on a plane region with mixed boundary conditions. We are interesting in solving a parametrization for one of the domain's boundary curves based on Cauchy data on the opposite boundary The problem is solved with a variation of alternating field technique on inverted plane. Let v be the harmonic conjugate of u. Then the function u(x, y) + iv(x, y) is analytic and it has an inverse x(u, v) + iy(u, v). The functions x and y satisfy Laplace's equation on a rectangle, and the unknown boundary curve maps to unknown boundary conditions in the rectangle. The unknown boundary conditions are solved using the alternating-field technique.
