Equivalences of real submanifolds in complex space
Abstract
We show that for any real-analytic submanifold M in CN there is a proper real-analytic subvariety V contained in M such that for any point p in M, any real-analytic submanifold M' in CN, and any point p' in M', the germs of the submanifolds M and M' at p and p' respectively are formally equivalent if and only if they are biholomorphically equivalent. More general results for k-equivalences are also stated and proved.
