The equivalence problem and rigidity for hypersurfaces embedded into hyperquadrics

P. Ebenfelt, X. Huang, D. Zaitsev

We consider the class of Levi nondegenerate hypersurfaces $M$ in $\bC^{n+1}$ that admit a local (CR transversal) embedding, near a point $p\in M$, into a standard nondegenerate hyp…
