Normal Forms for Nonintegrable Almost Cr Structures
We propose two constructions extending the Chern-Moser normal form to non-integrable Levi-nondegenerate (hypersurface type) almost CR structures. One of them translates the ChernMoser normalization into pure intrinsic setting, whereas the other directly extends the (extrinsic) Chern-Moser normal form by allowing non-CR embeddings that are in some sense “maximally CR”. One of the main difference...
متن کاملNew Normal Forms for Levi-nondegenerate Hypersurfaces
In this paper we construct a large class of new normal forms for Levi-nondegenerate real hypersurfaces in complex spaces. We adopt a general approach illustrating why these normal forms are natural and which role is played by the celebrated Chern-Moser normal form [CM74]. The latter appears in our class as the one with the ”maximum normalization” in the lowest degree. However, there are other n...
متن کاملEmbedding of Pseudoconvex Cr Manifolds of Levi-forms with One Degenerate Eigenvalue
Suppose that M is an abstract smoothly bounded orientable CR manifold of dimension 2n − 1 with a given integrable CR structure S of dimension n− 1. Since M is orientable, there are a smooth real nonvanishing 1-form η and a smooth real vector field X0 on M so that η(X) = 0 for all X ∈ S and η(X0) = 1. We define the Levi form of S on M by iη([X ′, X ′′]), X ′, X ′′ ∈ S. We may assume that M ⊂ M̃ ,...
متن کامل1 F eb 2 00 6 Homogeneous Levi degenerate CR - manifolds in dimension 5
Levi nondegenerate real-analytic hypersurfaces M ⊂ are well understood due to the seminal results of Tanaka [17] and Chern-Moser[5], where a complete set of local invariants for M has been defined. At the other extreme are those hypersurfaces which are locally CR-equivalent to a product M ×, (take the real hyperplanes in as a simple example). In-between there is a huge and much less underst...
متن کاملThe Equivalence and the Embedding Problems for Cr-structures of Any Codimension
We give a solution to the equivalence and the embedding problems for smooth CRsubmanifolds of complex spaces (and, more generally, for abstract CR-manifolds) in terms of complete differential systems in jet bundles satisfied by all CR-equivalences or CR-embeddings respectively (local and global). For the equivalence problem, the manifolds are assumed to be of finite type and finitely nondegener...
