Abstract

We consider smooth deformations of the CRCR structure of a smooth 22-pseudoconcave compact CRCR submanifold M\textsf{M} of a reduced complex analytic variety X\textsf{X} outside the intersection DMD\,{\cap}\,\textsf{M} with the support DD of a Cartier divisor of a positive line bundle FX.\texttt{F}_{\textsf{X}}. We show that nearby structures still admit projective CRCR embeddings. Special results are obtained under the additional assumptions that X\textsf{X} is a projective space or a Fano variety.
