Journal of Convex Analysis 30 (2023), No. 1, 343--358 Copyright Heldermann Verlag 2023 Diffeomorphism Groups of Convex Polytopes Helge Gloeckner Institut für Mathematik, Universität Paderborn, Germany glockner@math.upb.de [Abstract-pdf] Let $M$ be a convex polytope in $\mathbb{R}^n$, with non-empty interior. We turn the group Diff$(M)$ of all $C^\infty$-diffeomorphisms of $M$ into a regular Lie group. Keywords: Polytope, polyhedron, diffeomorphism group, infinite-dimensional Lie group, regularity, manifold with corners, local addition. MSC: 58D05; 22E65, 46T05, 46T10, 52B11, 52B15, 52B70.
