Oblique Pseudoinverses of Multipliers

Jerielle V. Malonzo, Diana T. Stoeva

Multipliers are operators on a Hilbert space that have been implicitly used in applications throughout the years. Multipliers are defined via three sequences and are mainly used in…

The mystery of Carleson frames

Ole Christensen, Marzieh Hasannasab, Friedrich Philipp +1

In 2016 Aldroubi et al. constructed the first class of frames having the form for a bounded linear operator on the underlying Hilbert space. In this paper w…

Weighted frames, weighted lower semi frames and unconditionally convergent multipliers

Peter Balazs, Rosario Corso, Diana Stoeva

In this paper we ask when it is possible to transform a given sequence into a frame or a lower semi frame by multiplying the elements by numbers. In other words, we ask when a give…

On compactly supported dual windows of Gabor frames

Diana T. Stoeva

The main purpose of the paper is to give a characterization of all compactly supported dual windows of a Gabor frame. As an application, we consider an iterative procedure for appr…

Dual frames compensating for erasures -- non-canonical case

Ljiljana Arambašić, Diana T. Stoeva

In this paper we study the problem of recovering a signal from frame coefficients with erasures. Suppose that erased coefficients are indexed by a finite set . Starting from a f…

On a characterization of Riesz bases via biorthogonal sequences

Diana T. Stoeva

It is well known that a sequence in a Hilbert space is a Riesz basis if and only if it is a complete Bessel sequence with biorthogonal sequence which is also a complete Bessel sequ…

Localization of Fréchet frames and expansion of generalized functions

Stevan Pilipović, Diana T. Stoeva

Matrix type operators with the off-diagonal decay of polynomial or sub-exponential types are revisited with weaker assumptions concerning row or column estimates, still giving the…

Operator representations of sequences and dynamical sampling

Ole Christensen, Marzieh Hasannasab, Diana T. Stoeva

This paper is a contribution to the theory of dynamical sampling. Our purpose is twofold. We first consider representations of sequences in a Hilbert space in terms of iterated act…

On the dual frame induced by an invertible frame multiplier

Diana T. Stoeva, Peter Balazs

Recently it has been established that given an invertible frame multiplier with semi-normalized symbol, a specific dual of any of the two involved frames can be determined for the…

On various R-duals and the duality principle

Diana T. Stoeva, Ole Christensen

The duality principle states that a Gabor system is a frame if and only if the corresponding adjoint Gabor system is a Riesz sequence. In general Hilbert spaces and without the ass…

On R-duals and the duality principle in Gabor analysis

Diana T. Stoeva, Ole Christensen

The concept of R-duals of a frame was introduced by Casazza, Kutyniok and Lammers in 2004, with the motivation to obtain a general version of the duality principle in Gabor analysi…

Can any unconditionally convergent multiplier be transformed to have the symbol (1) and Bessel sequences by shifting weights?

Diana T. Stoeva, Peter Balazs

Multipliers are operators that combine (frame-like) analysis, a multiplication with a fixed sequence, called the symbol, and synthesis. They are very interesting mathematical objec…
