Solution the Dirichlet Problem for Multiply Connected Domain Using Numerical Conformal Mapping

Abstract

© 2019, Springer Nature Switzerland AG. We present a method for construction of continuous approximate 2D Dirichlet problems solutions in an arbitrary multiply connected domain with a smooth boundary. The method is based on integral equations solution which is reduced to a linear system solution and does not require iterations. Unlike the Fredholm’s solution of the problem ours applies not a logarithsmic potential of a double layer but the properties of Cauchy integral boundary values. We search for the solution of the integral equation in the form of Fourier polynomial with the coefficients being the solution of a linear equation system. The continuous solution of Dirichlet problem is the real part of a Cauchy integral.
