On the boundedness of dilation operators in the context of Triebel-Lizorkin-Morrey spaces
Marc Hovemann, Markus Weimar
In this paper we study the behavior of dilation operators with in the context of Triebel-Lizorkin-Morrey spaces $\mathcal{E}^{s}_{u,p,q…

Adaptive Bivariate Quarklet Tree Approximation via Anisotropic Tensor Quarklets
Marc Hovemann
This paper deals with near-best approximation of a given bivariate function using elements of quarkonial tensor frames. For that purpose we apply anisotropic tensor products of the…
