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...

We propose a unified normal form for all Levi-nondegenerate hypersurface type almost CR structures.
متن کاملNormal forms and invariants for 2-dimensional almost-Riemannian structures
Two-dimensional almost-Riemannian structures are generalized Riemannian structures on surfaces for which a local orthonormal frame is given by a Lie bracket generating pair of vector fields that can become collinear. Generically, there are three types of points: Riemannian points where the two vector fields are linearly independent, Grushin points where the two vector fields are collinear but t...
متن کاملReducing almost Lagrangian structures and almost CR geometries to partially integrable structures
This paper demostrates a method for analysing almost CR geometries (H, J), by uniquely defining a partially integrable structure (H,K) from the same data. Thus two almost CR geometries (H,J) and (H ′, J ′) are equivalent if and and only if they generate isomorphic induced partially integrable CR geometries (H,K) and (H ′, K′), and the set of CR morphisms between these spaces contains an element...
