Approximation and convergence properties of formal CR-maps Academic Article uri icon


  • Let M N be a minimal real-analytic CR-submanifold and M N a real-algebraic subset through points p M and p M respectively. We show that that any formal (holomorphic) mapping f: ( N, p) ( N p), sending M into M, can be approximated up to any given order at p by a convergent map sending M into M. If M is furthermore generic, we also show that any such map f, that is not convergent, must send (in an appropriate sense) M into the set E M of points of D'Angelo infinite type. Therefore, if M does not contain any nontrivial complex-analytic subvariety through p, any formal map f sending M into M is necessarily convergent. 2002 Acadmie des sciences/ditions scientifiques et mdicales Elsevier SAS.
