On equivalence problem for 2--nondegenerate CR geometries with simple models (1906.00848v3)
Published 3 Jun 2019 in math.DG and math.CV
Abstract: In this article, we solve the equivalence problem for 2--nondegenerate CR geometries that have (at every point) a homogeneous space $G/H$ as a maximally symmetric model for $G$ simple real Lie group of CR automorphisms. This completes the classification of real submanifolds in complex space that are maximally symmetric models with a real simple CR automorphism group. In particular, we construct (local) embeddings of these models into complex space.
