Abstract

The conjugate function method is an algorithm for numerical computation of conformal mappings for simply and multiply connected domains on surfaces. In this paper the conjugate function method is generalized and refined to achieve the same level of accuracy on simply and multiply connected planar domains and Riemann surfaces. The main challenge addressed here is the accurate and efficient construction of the conjugate problem for multiply connected domains. The method relies on high-order finite element methods which allow for highly accurate computations of mappings on surfaces, including domains of complex boundary geometry containing strong singularities and cusps. The efficacy of the proposed method is illustrated via an extensive set of numerical experiments with error estimates.
