影响因子.Approximation Theory, Wavelets and Applications. drawstogether the latest developments in the subject, provides directionsfor future research, and paves the way for collaborative research. Themain topics covered include constructive multivariate approximation,theory of splines, spline wavelets, polynomial and trigonometricwavelets, interpolation theory, polynomial and rational approximation.Among the scientific applications were de-noising using wavelets,including the de-noising of speech and images, and signal and digitalimage processing. In the area of the approximation of functions themain topics include multivariate interpolation, quasi-interpolation,polynomial approximation with weights, knot removal for scattereddata, convergence theorems in Padé theory, Lyapunov theory inapproximation, Neville elimination as applied to shape preservingpresentation of curves, interpolating positive linear operators,interpolation from a convex subset of Hilbert space, and interpolationon the triangle and simplex. .Wavelet theory is growing extremely rapidly and has applications whichwill interest readers in the physical, medical, engineering and socialsciences. .

Approximation and Interpolation on Spheres,ss that has been made in the approximation of functions defined on spheres. For practical purposes, the sphere of greatest interest would appear to be S., since it serves as a (flawed) model of the Earth’s surface. There is every reason to believe that the new approximation methods now being develop

Exploring Covariance, Consistency and Convergence in Pade Approximation Theory, approximant .. of degree . in the numerator and degree . in the denominator, the Padé operator .. . The fact that the Padé approximant is a rational function gives rise to a number of interesting questions. Since the concept of Padé approximant is defined both for univariate and multivariate functi

Knot Removal for Scattered Data,tion of a function defined on scattered data, without perturbing the approximation more than a given tolerance. The method removes some (or all) of the interior knots. The number and location of these knots are determined automatically. Applications are in approximation of data, data storage and ima

Wavelets on the Interval,pted to a bounded interval. The two approaches of Meyer and Cohen-Daubechies-Vial to adapt Daubechies scaling functions and wavelets to .. [0, 1] are outlined, as well as the B-spline approach by Chui-Quak together with related algorithmic considerations of Quak-Weyrich.

Can Irregular Subdivisions Preserve Convexity?,ting surfaces that can be irregular in some case. Moreover, it seems to be suitable to preserve the convexity of the Bézier net defined over the triangle since it is . with the mid-point splitting. This property is proved by means of the algorithm used to define the scheme.
