AbstractThis paper is devoted to the analysis of multiscale approximation schemes in the context of multiresolution analysis. We have particular interest in expansions where the approximation strategies are obtained in terms of discrete convolutions of function point values with some specific weights. In the first part, three cases are considered: interpolation, quasi-interpolation and discrete projection. Some aspects are analyzed, such as algorithm of construction, accuracy, and alternative multiscale implementations. The second part is dedicated to hybrid formulations for the discretization of nonlinear differential operators. The idea is to combine two different approximation shcemes: one is used for functions or linear terms; another one, defined in terms of function point values, is used for nonlinear operations. In a multilevel setting, a pseudo-wavelet representation is introduced by means of the alternative multiscale algorithms. Taking the bilinear advection operator as a model, we estabilish the consistency of the discretizations in terms of the order of the truncation error.
