ANALYSIS AND APPROXIMATION THEORY SEMINAR UNIVERSITY OF ALBERTA Construction of compactly supported biorthogonal wavelets in L 2 (IR s

open access: yes, 2007
: This paper presents a general construction of compactly supported biorthogonal wavelets in L 2 (IR s ). In particular, a concrete method for the construction of bivariate compactly supported biorthogonal wavelets of increasing smoothness is provided.

Approximation by Radial Basis Functions with Finitely Many Centers

open access: yes, 1996
: Interpolation by translates of "radial" basis functions \Phi is optimal in the sense that it minimizes the pointwise error functional among all comparable quasi--interpolants on a certain "native" space of functions F \Phi .

Best Near-Interpolation By Curves: Existence And Convergence

open access: yes, 1999
. In this paper, the conditions derived in [10] for the existence of minimizers to the nonlinear problem of best \interpolation" by curves are extended to the problem of best \near-interpolation" by curves that meet arbitrary sets, such as ...

Dimension and Local Bases of Homogeneous Spline Spaces

open access: yes, 1995
. Recently, we have introduced spaces of splines defined on triangulations lying on the sphere or on sphere-like surfaces. These spaces arose out of a new kind of Bernstein-B'ezier theory on such surfaces.

Splines on Riemannian Manifolds and a Proof of a Conjecture by Wahba

open access: yes, 1999
This paper extends spline methods to compact Riemannian manifolds in an rkhs setting. The approach is to use the mathematical framework of rkhs, along with integrating spectral geometry associated with compact Riemannian manifolds.

The Apolar Bilinear Form in Geometric Modeling

open access: yes, 1998
Some recent methods of Computer Aided Geometric Design are related to the apolar bilinear form, an inner product on the space of homogeneous multivariate polynomials of a fixed degree, already known in 19th century invariant theory.

Approximation From Shift-Invariant Subspaces of ...

open access: yes, 1991
: A complete characterization is given of closed shift-invariant subspaces of L 2 (IR d ) which provide a specified approximation order. When such a space is principal (i.e., generated by a single function), then this characterization is in terms of ...
