Hyperbolic wavelet analysis of classical isotropic and anisotropic Besov-Sobolev spaces
M. Schäfer, T. Ullrich, B. Vedel
In this paper we introduce new function spaces which we call anisotropic hyperbolic Besov and Triebel-Lizorkin spaces. Their definition is based on a hyperbolic Littlewood-Paley an…

A higher order Faber spline basis for sampling discretization of functions
Nadiia Derevianko, Tino Ullrich
This paper is devoted to the question of constructing a higher order Faber spline basis for the sampling discretization of functions with higher regularity than Lipschitz. The basi…

Entropy numbers of finite dimensional mixed-norm balls and function space embeddings with small mixed smoothness
Sebastian Mayer, Tino Ullrich
We study the embedding and prove matching bounds for the entropy numbers provided that an…
