DESCRIPTION:Many problems in nonparametric statistics require the applicat
 ion of deconvolution procedures\, e.g. density estimation based on contami
 nated data\, errors-in-variables problems in nonparametric regression\, im
 age deblurring. The current talk focuses on rarely studied types of error 
 densities whose Fourier transforms have some zeros and show oscillatory be
 haviour. New methods are introduced for those deconvolution problems. The 
 optimal convergence rates are derived in several settings. The finite-samp
 le performance is studied by numerical simulations. \n\n
