Wavelet orthonormal bases for nonexpansive dilations
Jordy Timo van Velthoven, Felix Voigtlaender
We construct wavelet orthonormal bases for nonexpansive dilations and integer translations that do not admit a wavelet set. In addition, these orthonormal bases do not satisfy the…

Classification of anisotropic local Hardy spaces and inhomogeneous Triebel-Lizorkin spaces
Jordy Timo van Velthoven, Felix Voigtlaender
This paper provides a characterization of when two expansive matrices yield the same anisotropic local Hardy and inhomogeneous Triebel-Lizorkin spaces. The characterization is in t…
