NON-MSF MRA WAVELETS

, 2017
In this article, we provide two classes of non-MSF MRA wavelets in L(R). The first arose through one-dimensional dyadic wavelet sets having two components, is an uncountable family, while the second one arose through a special kind of MRA wavelet sets ...

A Hilbert C*-module admitting no frames

, 2009
We show that every infinite-dimensional commutative unital C*-algebra has a Hilbert C*-module admitting no frames. In particular, this shows that Kasparov's stabilization theorem for countably generated Hilbert C*-modules can not be extended to arbitrary

Characterization and Construction of Phase Retrievable Sequences

Journal of Mathematics, Volume 2025, Issue 1, 2025.
In this paper, we study phase retrievable sequences and give a characterization of phase retrievability of a sequence of bounded linear operators on a Hilbert space H; in particular, for H=l2dℂ. We also give several approaches for constructing phase retrievable sequences. Then, we investigate the property of phase retrievable for g‐frames and frames.

New forms of bilateral inequalities for K-g-frames

Demonstratio Mathematica
In this work, several bilateral inequalities for KK-gg-frames in subspaces are established, drawing support from two kinds of operators induced, respectively, by the KK-gg-frame itself and the KK-dual pair, which, compared with previous ones concerning ...

Shearlet approximations to the inverse of a family of linear operators

, 2013
The Radon transform plays an important role in applied mathematics. It is a fundamental problem to reconstruct images from noisy observations of Radon data. Compared with traditional methods, Colona, Easley and etc.

Iterations of the generalized Gram-Schmidt procedure for generating Parseval frames [PDF]

, 2016
In this paper we describe some properties of the generalized Gram-Schmidt procedure (GGSP) for generating Parseval frames which was first introduced by Casazza and Kutyniok [A generalization of Gram-Schmidt orthogonalization generating all Parseval ...

Counterexamples to the B-spline conjecture for Gabor frames

, 2015
The frame set conjecture for B-splines $B_n$, $n \ge 2$, states that the frame set is the maximal set that avoids the known obstructions. We show that any hyperbola of the form $ab=r$, where $r$ is a rational number smaller than one and $a$ and $b ...
