On Homogeneous Decomposition Spaces and Associated Decompositions of Distribution Spaces
Zeineb Al-Jawahri, Morten Nielsen
A new construction of decomposition smoothness spaces of homogeneous type is considered. The smoothness spaces are based on structured and flexible decompositions of the frequency…

Weighted Thresholding and Nonlinear Approximation
Emil Solsbæk Ottosen, Morten Nielsen
We present a new method for performing nonlinear approximation with redundant dictionaries. The method constructs an term approximation of the signal by thresholding with respe…

Nonlinear approximation with nonstationary Gabor frames
Emil Solsbæk Ottosen, Morten Nielsen
We consider sparseness properties of adaptive time-frequency representations obtained using nonstationary Gabor frames (NSGFs). NSGFs generalize classical Gabor frames by allowing…
