Macro-element Hierarchical Riesz Bases
Lecture Notes in Computer Science, 2014We show that a nested sequence of C r macro-element spline spaces on quasi-uniform triangulations gives rise to hierarchical Riesz bases of Sobolev spaces H s (Ω ...

Riesz bases and their dual modular frames in Hilbert C∗-modules [PDF]
Journal of Mathematical Analysis and Applications, 2008 We investigate dual frames of modular frames and Riesz bases in Hilbert C∗-modules. In Hilbert C∗-modules, a Riesz basis may have many dual modular frames, and it may even admit two different dual modular frames both of which are Riesz bases.

Characterization of Riesz bases of wavelets generated from multiresolution analysis [PDF]
Applied and Computational Harmonic Analysis, 2007 We investigate Riesz bases of wavelets generated from multiresolution analysis. This investigation leads us to a study of refinement equations with masks being exponentially decaying sequences. In order to study such refinement equations we introduce the

A system of vectors in a Hilbert space \(H\) is a Riesz basis for \(H\) if there is an automorphism of \(H\) carrying the system onto an orthonormal basis for \(H\). The paper under review presents several results which involve Riesz bases either in themselves or in their proofs (or both). The first theorem, proved independently by \textit{M. Horvath} [
