A mathematical study of the charge simulation method. I. (English) Zbl 0662.65100

The charge simulation method is a means to solve the first boundary value problem for the Laplace equation in a two-dimensional domain. It consists in determining N charges located outside the domain by collocation at N boundary points. The authors consider a circular domain, give a condition for unique solvability and an error estimate which shows an exponential rate of convergence for analytic boundary data. They conclude with remarks on more general domains.
