Unitary Extension Principle for Nonuniform Wavelet Frames in $L^2(\mathbb{R})$

Functional Analysis 2022-07-14 v4

Abstract

We study the construction of nonuniform tight wavelet frames for the Lebesgue space L2(R)L^2(\mathbb{R}), where the related translation set is not necessary a group. The main purpose of this paper is to prove the unitary extension principle (UEP) and the oblique extension principle (OEP) for construction of multi-generated nonuniform tight wavelet frames for L2(R)L^2(\mathbb{R}). Some examples are also given to illustrate the results.
