,Wavelets — With Emphasis on Spline-Wavelets and Applications to Signal Analysis,out a year ago for the Lancaster workshop. However, this present article is intended to be self-contained, as much as possible, with the danger of some overlapping. It is again written from the point of view of an approximation theorist with special interest in spline functions and applications to s

Pade Approximation in One and More Variables,from the . algorithm are given for the normal case as well as for a non-normal table composed of square blocks. Convergence of UPA for meromorphic functions and continuity of the univariate Padé operator are discussed..The same approximation problem is considered in the multivariate case. General or

A Tutorial on Multivariate Wavelet Decomposition, di Maratea, Italy, Spring 1991. In the style of the Nato ASI, we have made these lectures nearly selfcontained. The published results we draw upon appear in the three papers [1, 2, 3], Nearly all of the material described here comes from joint work with R. Q. Jia.

Using The Refinement Equation For The Construction of Pre-Wavelets VI: Shift Invariant Subspaces,chelli [2] can be extended to subspaces of ..(ℝ.) generated by a finite number of compactly supported functions. Specifically, we let Φ: ℝ. → ℂ. be a vector of . functions Φ = (φ.,…,φ.). AS in our previous article in these proceedings we will be concerned with wavelet decomposition in ..(ℝ.) built u

Error Estimates For Near-Minimax Approximations,minimax error E.(f) is expressed in terms of the (n+1)th derivative of f. We define a near-minimax projection P from C.[-1, 1] to P. as one where ∥f - Pf∥. can similarly be expressed in terms of the (n+l)th derivative of f. We show that some of the most familiar polynomial approximations are particu
