Approximation with scaled shift-invariant spaces by means of quasi-projection operators
The work of de Boor and Fix on spline approximation by quasiinterpolants has had far-reaching influence in approximation theory since publication of their paper in 1973. In this paper, we further develop their idea and investigate quasi-projection operators.We give sharp estimates in terms ofmoduli of smoothness for approximation with scaled shift-invariant spaces by means of quasi-projection o...
متن کاملApproximation by quasi-projection operators in Besov spaces
In this paper, we investigate approximation of quasi-projection operators in Besov spaces B p,q, μ > 0, 1 ≤ p, q ≤ ∞. Suppose I is a countable index set. Let (φi)i∈I be a family of functions in Lp(IR), and let (φ̃i)i∈I be a family of functions in Lp̃(IR), where 1/p+ 1/p̃ = 1. Let Q be the quasi-projection operator given by
متن کاملApproximation from Shift-invariant Spaces by Integral Operators∗
We investigate approximation from shift-invariant spaces by using certain integral operators and discuss various applications of this approximation scheme. We assume that our integral operators commute with shift operators and that their kernel functions decay at a polynomial rate. We prove that the approximation order provided by such an integral operator is m if and only if the integral opera...
متن کاملShift Invariant Spaces and Shift Preserving Operators on Locally Compact Abelian Groups
We investigate shift invariant subspaces of $L^2(G)$, where $G$ is a locally compact abelian group. We show that every shift invariant space can be decomposed as an orthogonal sum of spaces each of which is generated by a single function whose shifts form a Parseval frame. For a second countable locally compact abelian group $G$ we prove a useful Hilbert space isomorphism, introduce range funct...
متن کاملQuasi-interpolation in shift invariant spaces
Let s ≥ 1 be an integer, φ : Rs → R be a compactly supported function, and S(φ) denote the linear span of {φ(· − k) : k ∈ Zs}. We consider the problem of approximating a continuous function f : Rs → R on compact subsets of Rs from the classes S(φ(h·)), h > 0, based on samples of the function at scattered sites in R s. We demonstrate how classical polynomial inequalities lead to the construction...
