Local geometric properties of real submanifolds in complex space

M Baouendi, P Ebenfelt, L Rothschild - Bulletin of the American …, 2000 - ams.org
We survey some recent results on local geometric properties of real submanifolds of
complex space. Our main focus is on the structure and properties of mappings between such …

A complete normal form for everywhere Levi degenerate hypersurfaces in

M Kolar, I Kossovskiy - arXiv preprint arXiv:1905.05629, 2019 - arxiv.org
$2 $-nondegenerate real hypersurfaces in complex manifolds play an important role in CR-
geometry and the theory of Hermitian Symmetric Domains. In this paper, we construct a …

On Convergent Poincar\'e-Moser Reduction for Levi Degenerate Embedded -Dimensional CR Manifolds

WG Foo, J Merker, TA Ta - arXiv preprint arXiv:2003.01952, 2020 - arxiv.org
Applying Lie's theory, we show that any $\mathcal {C}^\omega $ hypersurface $ M^
5\subset\mathbb {C}^ 3$ in the class $\mathfrak {C} _ {2, 1} $ carries Cartan-Moser chains of …

The geometry of hyperbolic and elliptic CR-manifolds of codimension two

G Schmalz, J Slovák - arXiv preprint math/9903046, 1999 - arxiv.org
The general theory of parabolic geometries is applied to the study of the normal Cartan
connections for all hyperbolic and elliptic 6-dimensional CR-manifolds of codimension two …

Invariants of elliptic and hyperbolic CR-structures of codimension 2

VV Ezhov, AV Isaev, G Schmalz - International Journal of …, 1999 - World Scientific
We reduce CR-structures on smooth elliptic and hyperbolic manifolds of CR-codimension 2
to parallelisms thus solving the problem of global equivalence for such manifolds. The …

Convergent normal form for real hypersurfaces at a generic Levi-degeneracy

I Kossovskiy, D Zaitsev - Journal für die reine und angewandte …, 2019 - degruyter.com
We construct a complete convergent normal form for a real hypersurface in ℂ N, N≥ 2, at a
generic Levi-degeneracy. This seems to be the first convergent normal form for a Levi …

[HTML][HTML] Convergent normal form and canonical connection for hypersurfaces of finite type in C2

I Kossovskiy, D Zaitsev - Advances in Mathematics, 2015 - Elsevier
We study the holomorphic equivalence problem for finite type hypersurfaces in C 2. We
discover a geometric condition, which is sufficient for the existence of a natural convergent …

Explicit construction of a Chern–Moser connection for CR manifolds of codimension two

G Schmalz, A Spiro - Annali di Matematica Pura ed Applicata, 2006 - Springer
In the present paper we suggest an explicit construction of a Cartan connection for an elliptic
or hyperbolic CR manifold M of dimension six and codimension two, ie a pair (P, ω) …

Global structures on CR manifolds via Nash blow-ups.

T Garrity - Michigan Mathematical Journal, 2000 - projecteuclid.org
Let X be a compact real (2n+ 2)-dimensional submanifold of the complex space Cn+ 2. For
generic such X at all but a finite number of points, the tangent space of X will have a 2n …
