Generalized coorbit space theory and inhomogeneous function spaces of Besov-Lizorkin-Triebel type

Holger Rauhut, Tino Ullrich

Coorbit space theory is an abstract approach to function spaces and their atomic decompositions. The original theory developed by Feichtinger and Gr{ö}chenig in the late 1980ies he…

Continuous characterizations of Besov-Lizorkin-Triebel spaces and new interpretations as coorbits

Tino Ullrich

We give characterizations for homogeneous and inhomogeneous Besov-Lizorkin-Triebel spaces in terms of continuous local means for the full range of parameters. In particular, we pro…

The Gelfand widths of $ℓ_{p}$ -balls for $0 < p \leq 1$

Simon Foucart, Alain Pajor, Holger Rauhut +1

We provide sharp lower and upper bounds for the Gelfand widths of $ℓ_{p}$ -balls in the $N$ -dimensional $ℓ_{q}^{N}$ -space for $0 < p \leq 1$ and $p < q \leq 2$ . Such estimates are highly…
