Abstract: | Summary. An additive Schwarz iteration is described for the fast resolution of linear ill-posed problems which are stabilized by Tikhonov
regularization. The algorithm and its analysis are presented in a general framework which applies to integral equations of
the first kind discretized either by spline functions or Daubechies wavelets. Numerical experiments are reported on to illustrate
the theoretical results and to compare both discretization schemes.
