Quarkonial analysis

Hans Triebel

The spaces $A_{p, q}^{s} (R^{n})$ with $A \in {B, F}$ , $s \in R$ and $0 < p, q \leq \infty$ are usually introduced in terms of Fourier--analytical decompositions. Relate…

Truncations and compositions in function spaces

Hans Triebel

These notes deal with some recent assertions about truncations $f \mapsto ∣ f ∣$ and compositions $f \mapsto g \circ f$ in the spaces $A_{p, q}^{s} (R^{n})$ , $A \in {B, F}$ .

Mapping properties of Fourier transforms

Hans Triebel

The paper deals with continuous and compact mappings generated by the Fourier transform between distinguished function spaces on $R^{n}$ . The degree of compactness will be m…
