On formal maps between generic submanifolds in complex space
Let H:(M,p)->(M',p') be a formal mapping between two germs of real-analytic
generic submanifolds in C^N with nonvanishing Jacobian. Assuming M to be
minimal at p and M' holomorphically nondegenerate at p', we prove the
convergence of the mapping H. As a consequence, we obtain a new convergence
result for arbitrary formal maps between real-analytic hypersurfaces when the
target does not contain any holomorphic curve. In the case when both M and M'
are hypersurfaces, we also prove the convergence of the associated reflection
function when M is assumed to be only minimal. This allows us to derive a new
Artin type approximation theorem for formal maps of generic full rank
