Resumen:
A two-step Wavelet-Landweber method is presented in this article. A wavelet expansion followed by thresholding constitutes the first step while the second consists of the application of a classical iterative Landweber method. Orders of convergence are obtained and it is shown that, under certain hypotheses, the two-step method is optimal. Finally, numerical results are presented for the case in which T is an integral operator.
