On the Interplay of Regularity and Decay in Case of Radial Functions I.   Inhomogeneous spaces
  We deal with decay and boundedness properties of radial functions belonging to Besov and Lizorkin-Triebel spaces. In detail we investigate the surprising interplay of regularity and decay. Our tools are atomic decompositions in combination with trace theorems.
