On CR embeddings of strictly pseudoconvex hypersurfaces into spheres in low dimensions
It follows from the 2004 work of the first author, X.Huang, and D. Zaitsev that any local CR embedding $f$ of a strictly pseudoconvex hypersurface $M^{2n+1}\subset \mathbb {C}^{n+1}$ into the sphere $\mathbb {S}^{2N+1}\subset \mathbb {C}^{N+1}$ is rigid, i.e. any other such local embedding is obtained from $f$ by composition with …
