چکیده

The regularity of a univariate compactly supported reenable function is known to be related to the spectral properties of an associated transfer operator. In the case of multivariate reenable functions with a general dilation matrix A, although factorization techniques, which are typically used in the univariate setting, are no longer applicable, we derive similar results that also depend on the spectral properties of A.

Multivariate Compactly Supported Fundamental Reenable Functions, Duals and Biorthogonal Wavelets

In areas of geometric modeling and wavelets, one often needs to construct a compactly supported reenable function with suucient regularity which is fundamental for interpolation (that means, (0) = 1 and () = 0 for all 2 Z s nf0g). Low regularity examples of such functions have been obtained numerically by several authors and a more general numerical scheme was given in RiS1]. This paper present...

Multivariate Compactly Supported Fundamental Re nable Functions

For a given continuous compactly supported reenable function that is fundamental (that means, () =), this paper presents several methods to construct, directly from , compactly supported fundamental reenable functions with higher regularity. Asymptotic regularity analyses of the constructions are given. These constructions immediately provide multivariate interpolatory subdivision schemes that ...

The Sobolev Regularity of Reenable Functions the Sobolev Regularity of Reenable Functions

Reenable functions underlie the theory and constructions of wavelet systems on the one hand, and the theory and convergence analysis of uniform subdivision algorithms. The regularity of such functions dictates, in the context of wavelets, the smoothness of the derived wavelet system, and, in the subdivision context, the smoothness of the limiting surface of the iterative process. Since the reen...
