Some Error Estimates for Wavelet Expansions.

S. Bertoluzza

We give some error estimate for the approximation of a function by its wavelet expansion. Moreover we consider a numerical procedure (quadrature rule) to compute the coefficients of the expansion of a given function with respect to a compactly supported wavelet basis, for which we give an error estimate in the W^s,p norm.
