Let s โฅ 1 be an integer, ฯ s โ be a compactly supported function, and S ฯ denote the linear span of ฯ โข -k k โ s . We consider the problem of approximating a continuous function f s โ on compact subsets of s from the classes S ฯ hโข , h > 0, based on samples of the function at scattered sites in s .

The motivation for this work is a recently constructed family of generators of shift invariant spaces with certain optimal approximation properties, but which are not refinable in the classical sense. We try to see whether, once the classical refinability requirement is removed, it is still possible
Under certain assumptions on the compactly supported function f ยฅ C(R d ), we propose two methods of selecting a function s from the scaled principal shiftinvariant space S h (f) such that s interpolates a given function f at a scattered set of data locations. For both methods, the selection scheme
We construct right shift invariant subspaces of index n, 1 [ n [ ., in a p spaces, 2 < p < ., and in weighted a p spaces.
In this paper the rearrangement-invariant hulls and kernels of the classes loc ] on a noncompact nondiscrete locally compact abelian group are characterized. The space L 1 loc & S$ of tempered distributions serves as the extended domain of the Fourier transform instead of the classical domain L 1 +
