Abstract

We study the deformation theory of CR maps in the positive codimensional case. In particular, we study structural properties of the {\em mapping locus} EE of (germs of nondegenerate) holomorphic maps H ⁣:(M,p)MH \colon (M,p) \to M' between generic real submanifolds MCNM \subset \mathbb C^N and MCNM' \subset \mathbb C^{N'}, defined to be the set of points pMp' \in M' which admit such a map with H(p)=pH(p) = p'. We show that this set EE is semi-analytic and provide examples for which EE posseses (prescribed) singularities.
