In the paper minimax rates of convergence for wavelet estimators are studied. The estimators are based on the shrinkage of empirical coefficients ฮฒjk of wavelet decomposition of unknown function with thresholds ฮป j . These thresholds depend on the regularity of the function to be estimated. In the p
