%0 Journal Article %T The Convenient Setting for Denjoy--Carleman Differentiable Mappings of Beurling and Roumieu Type %A Andreas Kriegl %A Peter W.

Applications to manifolds of mappings are given: The group of $\mathcal C$-diffeomorphisms is a regular $\mathcal C$-Lie group if $\mathcal C \supseteq C^\omega$, but not better. %U http://arxiv.org/abs/1111.1819v3
