Comparison of some notions of \(C^k\)-maps in multi-variable non-archimedian analysis. (English) Zbl 1173.26326

The author compares various definitions of \(C^k\)-maps of open subsets of finite-dimensional vector spaces over a complete valued field. It is shown that the notions of \(C^k\)-maps defined by Schikhof, De Smedt, Bertram, Neeb and the author are identical. Various notions of Hölder differentiable maps are introduced and compared.
