The first half of the present memoir is devoted to KAM theory and \textsc{Arnold}'s theorem for several planets in space, as detailed in one preprint and one article:\footnote{\url{http://people.math.jussieu.fr/~fejoz/articles.html}} -- ''Twisted conjugacies and invariant tori theorems~\cite{Fejoz:2010a}. I reprove a normal form theorem due to \textsc{Moser}~\cite{Moser:1967}, for perturbations of a vector field having a Diophantine quasi-periodic invariant torus. This normal form, which I call a \emph{twisted conjugacy}, is a gateway to invariant tori theorems of \textsc{Kolmogorov}, \textsc{Arnold}, \textsc{Rüssmann} and \textsc{Herman}, as well as to some other theorems, for example for dissipative vector fields. I introduce a \emph{hypo...
