Heisenberg uncertainty inequalities for locally compact abelian groups
Hartmut Führ
We prove a version of Heisenberg's uncertainty principle for a rather general class of locally compact abelian groups. We compare the lower bound provided by our approach with the…
Translation complete subgroups of affine Weyl-Heisenberg groups and their generalized wavelet systems
Hartmut Führ, Narjes Rashidi
The -dimensional affine Weyl-Heisenberg group is a Lie group typically parameterized as $G_{aWH} = \mathbb{T} \times \mathbb{R}^n \times \widehat{\mathbb{R}^n} \times \mathrm{GL…
Cheeger Bounds for Stable Phase Retrieval in Reproducing Kernel Hilbert Spaces
Hartmut Führ, Max Getter
Phase retrieval seeks to reconstruct a signal from phaseless intensity measurements and, in applications where measurements contain errors, demands stable reconstruction. We study…
Classifying Wavelet Coorbit Spaces in Dimension 2
Noufal Asharaf, Hartmut Führ, Vaishakh Jayaprakash
Coorbit spaces provide a rigorous framework for the assessment of the approximation theoretic properties of generalized wavelet systems. It is therefore useful to understand when t…
Coorbit spaces associated to integrably admissible dilation groups
Hartmut Führ, Jordy Timo van Velthoven
This paper considers coorbit spaces parametrized by mixed, weighted Lebesgue spaces with respect to the quasi-regular representation of the semi-direct product of Euclidean space a…
Groups with frames of translates
Hartmut Fuhr, Vignon Oussa
Let be a locally compact group with left regular representation We say that admits a frame of translates if there exist a countable set and $φ\in L^{2…
