In Chapter 4 of 28 Triebel proved two theorems concerning pointwise multipliers and diffeomorphisms in function spaces \documentclass{article}\usepackage{amssymb}\begin{document}\pagestyle{empty}$B^s_{p,q}(\mathbb {R}^n)$\end{document} and \documentclass{article}\usepackage{amssymb}\begin{document}\pagestyle{empty}$F^{s}_{p,q}(\mathbb {R}^n)$\end{document}. In each case he presented two approaches, one via atoms and one via local means. While the approach via atoms was very satisfactory concerning the length and simplicity, only the rather technical approach via local means proved the theorems in full generality.
