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…

An unbounded operator theory approach to lower frame and Riesz-Fischer sequences

Peter Balazs, Mitra Shamsabadi

Frames and orthonormal bases are naturally linked to bounded operators. To tackle unbounded operators those sequences might not be well suited. This has already been noted by von N…

Redundant Representation of Operators

Peter Balazs, Georg Rieckh

To be able to solve operator equations numerically a discretization of those operators is necessary. In the Galerkin approach bases are used to achieve discretized versions of oper…

Admissibility for -Modulation Spaces

Peter Balazs, Dominik Bayer, Michael Speckbacher

This paper is concerned with frame decompositions of -modulation spaces. These spaces can be obtained as coorbit spaces for square-integrable representations of the affine Weyl-…

The continuous nonstationary Gabor transform on LCA groups with applications to representations of the affine Weyl-Heisenberg group

Michael Speckbacher, Peter Balazs

In this paper we introduce and investigate the concept of reproducing pairs which generalizes continuous frames. We will introduce a concept that represents a unifying way to look…
