Combinations of multivariate averages
Rate of approximation of combinations of averages on the spheres is shown to be equivalent to K-functionals yielding higher degree of smoothness. Results relating combinations of averages on rims of caps of spheres are also achieved. © 2004 Elsevier Inc. All rights reserved. MSC: 41A17; 41A63; 26B33; 46E35
متن کاملMultivariate complex B-splines and Dirichlet averages
The notion of complex B-spline is extended to a multivariate setting by means of ridge functions employing the known geometric relationship between ordinary B-splines and multivariate B-splines. To derive properties of complex B-splines in R, 1 < s ∈ N, the Dirichlet average has to be generalized to include infinite dimensional simplices △∞. Based on this generalization several identities of mu...
متن کاملApproximating Multivariate Tempered Stable Processes
Abstract. We give a simple method to approximate multidimensional exponentially tempered stable processes and show that the approximating process converges in the Skorokhod topology to the tempered process. The approximation is based on the generation of a random angle and a random variable with a lower dimensional Lévy measure. We then show that if an arbitrarily small normal random variable i...
متن کاملApproximating Averages of Geometrical and Combinatorial Quantities by Kfir
We look into the problem of estimating the average of quantities relating to combinatorial and geometrical objects. In all the cases we study it is possible to get the exact average of these quantities by using the trivial algorithm that calculates the average by obtaining all the quantities. Using the underlying structure of these problems we are able to obtain faster algorithms that approxima...
متن کاملTractability of Approximating Multivariate Linear Functionals
We review selected tractability results for approximating linear tensor product functionals defined over reproducing kernel Hilbert spaces. This review is based on Volume II of our book [5] Tractability of Multivariate Problems. In particular, we show that all non-trivial linear tensor product functionals defined over a standard tensor product unweighted Sobolev space suffer the curse of dimens...
