备注：: 11 pages, 8 figures

英文摘要：

A prescription for constructing dictionaries for cardinal spline spaces on a compact interval is provided. It is proved that such spaces can be spanned by dictionaries which are built by translating a prototype B-spline function of fixed support into the knots of the required cardinal spline space. This implies that cardinal spline spaces on a compact interval can be spanned by dictionaries of cardinal B-spline functions of broader support that the corresponding basis function.

Adaptive non-uniform B-spline dictionaries on a compact interval

Non-uniform B-spline dictionaries on a compact interval are discussed. For each given partition, dictionaries of B-spline functions for the corresponding spline space are constructed. It is asserted that, by dividing the given partition into subpartitions and joining together the bases for the concomitant subspaces, slightly redundant dictionaries of B-splines functions are obtained. Such dictionaries are proved to span the spline space associated to the given partition. The proposed construction is shown to be potentially useful for the purpose of sparse signal representation. With that goal …

From cardinal spline wavelet bases to highly coherent dictionaries

Wavelet families arise by scaling and translations of a prototype function, called the {\em {mother wavelet}}. The construction of wavelet bases for cardinal spline spaces is generally carried out within the multi-resolution analysis scheme. Thus, the usual way of increasing the dimension of the multi-resolution subspaces is by augmenting the scaling factor. We show here that, when working on a compact interval, the identical effect can be achieved without changing the wavelet scale but reducing the translation parameter. By such a procedure we generate a redundant frame, called a {\em{diction…

The Asymptotic Behaviour of the $m$-th Order Cardinal $B$-Spline wavelet

It is well-known that the $m$-th order cardinal $B$-spline wavelet, $ψ_{m},$ decays exponentially. Our aim in this paper is to determine the exact rate of this decay and thereby to describe the asymptotic behaviour of $ψ_{m}$.

Convergence properties of spline-like cardinal interpolation operators acting on $l^p$ data

If $f\in \{f\in L^p(\mathbb{R}): f(x)=\int_{-π}^πe^{ixξ}dβ(ξ), β\in B.V.([-π,π]) \}$, then $f$ is determined by its samples on the integers by taking an appropriate limit. Specifically, $\| f - L_{ϕ_α}f \|_{L^p(\mathbb{R})}\to 0$ as $α\to\infty$ provided that $\{ϕ_α: α\in A\}$ is what we call a spline-like family of cardinal interpolators.

Quaternionic Fundamental Cardinal Splines: Interpolation and Sampling

B-splines $B_{q}$, $\Sc q > 1$, of quaternionic order $q$, for short quaternionic B-splines, are quaternion-valued piecewise Müntz polynomials whose scalar parts interpolate the classical Schoenberg splines $B_{n}$, $n\in\N$, with respect to degree and smoothness. As the Schoenberg splines of order $\geq 3$, they in general do not satisfy the interpolation property $B_{q}(n-k) = δ_{n,k}$, $n,k\in\Z$. However, the application of the interpolation filter $1/\sum\limits_{k\in\Z} \widehat{B}_{q}(ξ+2 πk)$---if well-defined---in the frequency domain yields a cardinal fundamental spline of quaternion…

Interpolation and Sampling with Exponential Splines of Real Order

The existence of fundamental cardinal exponential B-splines of positive real order $σ$ is established subject to two conditions on $σ$ and their construction is implemented. A sampling result for these fundamental cardinal exponential B-splines is also presented.

Splines and Fractional Differential Operators

Several classes of classical cardinal B-splines can be obtained as solutions of operator equations of the form $Ly = 0$ where $L$ is a linear differential operator of integral order. (Cf., for instance, \cite{akhiezer,Golomb,Krein,micchelli,schoenberg}.) In this article, we consider classes of generalized B-splines consisting of cardinal polynomial B-splines of complex and hypercomplex orders and cardinal exponential B-splines of complex order, and derive the fractional linear differential operators that are naturally associated with them. For this purpose, we also present the spaces of distri…

Quarklet Characterizations for Triebel-Lizorkin Spaces

In this paper we prove that under some conditions on the parameters the one-dimensional Triebel-Lizorkin spaces $ F^{s}_{r,q}(\mathbb{R}) $ can be described in terms of quarklets. So for functions from Triebel-Lizorkin spaces we obtain a quarkonial decomposition as well as a new equivalent quasi-norm. For that purpose we use quarklets that are constructed out of biorthogonal compactly supported Cohen-Daubechies-Feauveau spline wavelets, where the primal generator is a cardinal B-spline. Moreover we introduce some sequence spaces apposite to our quarklet system and study their properties. Final…
