Abstract:
We study various questions related to the smoothness
of a real submanifold \(M\) which is invariant under a family of real-analytic or holomorphic
diffeomorphisms. We show that in various situations it is possible to conclude that \(M\)
is necessarily real-analytic (or the same smoothness of the diffeomorphisms involved if
these are not analytic). The prolongation method we use also allows to recover some known
results by employing relatively simple tools.
