  • Beschreibung: <p>We discuss the growth envelopes of Fourier-analytically defined Besov and Triebel-Lizorkin spaces $B_{p,q}^s (R^n )$ and $F_{p,q}^s (R^n )$ in the limiting case $s = \sigma _{p\,} : = \,n\,\max (\frac{1}{p}\, - \,1,0)$ . These results may also be reformulated as optimal embeddings into the scale of Lorentz spaces $L_{p,q} (R^n )$ . We close several open problems outlined already in [H. Triebel, The structure of functions, Birkhäuser, Basel, 2001] and explicitly stated in [D. D. Haroske, Envelopes and sharp embeddings of function spaces, Chapman &amp; Hall/CRC, Boca Raton, FL, 2007].</p>
