On groups of Hölder diffeomorphisms and their regularity

David Nicolas Nenning, Armin Rainer

We study the set $D^{n, β} (R^{d})$ of orientation preserving diffeomorphisms of $R^{d}$ which differ from the identity by a Hölder $C_{0}^{n, β}$ -mapping, where $n…

Extension of Whitney jets of controlled growth

Armin Rainer, Gerhard Schindl

We revisit Whitney's extension theorem in the ultradifferentiable Roumieu setting. Based on the description of ultradifferentiable classes by weight matrices, we extend results on…
