Wavelet approximations for first kind boundary integral equations on polygons. (English) Zbl 0863.65074

The present paper is devoted to the analysis of wavelet based symmetric Galerkin schemes for boundary integral equations of the first kind on polygonal domains in \(\mathbb{R}^2\). The results hold also for first kind boundary integral equations arising in the problem of plane elasticity on polygonal domains. The numerical experiments indicate that the estimates of the consistency error due to the matrix compressions obtained are efficient.
