N. Dyn et A. Ron, MULTIRESOLUTION ANALYSIS BY INFINITELY DIFFERENTIABLE COMPACTLY SUPPORTED FUNCTIONS, Applied and computational harmonic analysis, 2(1), 1995, pp. 15-20
The paper is concerned with the introduction and study of multiresolut
ion analysis based on the up function, which is an infinitely differen
tiable function supported on [0,2]. Such analysis is, necessarily, non
stationary. It is shown that the approximation orders associated with
the corresponding spaces are spectral, thus making the spaces attracti
ve for the approximation of very smooth functions. (C) 1995 Academic P
