چکیده
Approximation orders of shift-invariant subspaces of L p (IR d), 2 p 1, generated by the shifts of one compactly supported function are considered. In that course, explicit approximation maps are constructed. The approach avoids quasi-interpolation and applies to stationary and non-stationary reenements. The general results are specialized to box spline spaces, to obtain new results on their approximation orders.

The L 2 - Approximation Orders of Principal Shift - Invariant Spaces Generated by a Radial Basis Function
Approximations from the L 2 -closure S of the nite linear combinations of the shifts of a radial basis function are considered, and a thorough analysis of the least-squares approximation orders from such spaces is provided. The results apply to polyharmonic splines, multiquadrics, the Gaussian kernel and other functions, and include the derivation of spectral orders. For stationary re nements i...
متن کاملApproximation from Shift - Invariant Subspaces of L 2 ( R d )
In this report, a summary of [1] is given. In [1] the authors provide a complete characterization of closed shift-invariant subspaces of L2(R) and the corresponding approximation order. The characterization of principal shift-invariant spaces is given in terms of the Fourier transform of the generator. The approximation order of a general shift-invariant space is the same as a suitably chosen p...
متن کاملSmooth Reenable Functions Provide Good Approximation Orders Smooth Reenable Functions Provide Good Approximation Orders
We apply the general theory of approximation orders of shift-invariant spaces of BDR1-3] to the special case when the nitely many generators L 2 (IR d) of the underlying space S satisfy an N-scale relation (i.e., they form a \father wavelet" set). We show that the approximation orders provided by such nitely generated shift-invariant spaces are bounded from below by the smoothness class of each...
متن کاملIntroduction to Shift-Invariant Spaces I: Linear Independence
Shift-invariant spaces play an increasingly important role in various areas of mathematical analysis and its applications. They appear either implicitly or explicitly in studies of wavelets, splines, radial basis function approximation, regular sampling, Gabor systems, uniform subdivision schemes, and perhaps in some other areas. One must keep in mind, however, that the shift-invariant system e...
متن کاملAn Upper Bound on the Approximation Power of Principal Shift-invariant Spaces
An upper bound on the Lp-approximation power (1 p 1) provided by principal shift-invariant spaces is derived with only very mild assumptions on the generator. It applies to both stationary and non-stationary ladders, and is shown to apply to spaces generated by (exponential) box splines, polyharmonic splines, multiquadrics, and Gauss kernel.
