On highly degenerate CR maps of spheres

Giuseppe della Sala, Bernhard Lamel, Michael Reiter +1

For we classify the -degenerate smooth CR maps of the three-dimensional unit sphere into the -dimensional unit sphere. Each of these maps has image being…

Deformations of CR maps and applications

Giuseppe della Sala, Bernhard Lamel, Michael Reiter

We study the deformation theory of CR maps in the positive codimensional case. In particular, we study structural properties of the {\em mapping locus} of (germs of nondegenera…

Sufficient and necessary conditions for local rigidity of CR mappings and higher order infinitesimal deformations

Giuseppe della Sala, Bernhard Lamel, Michael Reiter

In this paper we continue our study of local rigidity for maps of CR submanifolds of the complex space. We provide a linear sufficient condition for local rigidity of finitely nond…

Jet determination of smooth CR automorphisms and generalized stationary discs

Florian Bertrand, Giuseppe Della Sala, Bernhard Lamel

We prove finite jet determination for (finitely) smooth CR diffeomorphisms of (finitely) smooth Levi degenerate hypersurfaces in by constructing generalized stat…

Curves homogeneous under analytic transformations

Giuseppe Della Sala

We call a subset of \emph{biholomorphically homogeneous} if for any two points there exists a neighborhood of and a biholomorphism $ψ:U\to ψ(U)\s…

Local and infinitesimal rigidity of hypersurface embeddings

Giuseppe Della Sala, Bernhard Lamel, Michael Reiter

We study local rigidity properties of holomorphic embeddings of real hypersurfaces in into real hypersurfaces in and show that infinitesimal conditions…

Riemann-Hilbert problems with constraints

Florian Bertrand, Giuseppe Della Sala

This paper is devoted to Riemann-Hilbert problems with constraints. We obtain results characterizing the existence of solutions as well as the dimension of the solution space in te…

Stationary discs for smooth hypersurfaces of finite type and finite jet determination

Florian Bertrand, Giuseppe Della Sala

We construct a finitely dimensional invariant manifold of holomorphic discs attached to a certain class of smooth pseudconvex hypersurfaces of finite type in $\C^2$, generalizing t…

Bergman spaces of natural G-manifolds

Giuseppe Della Sala, Joe J. Perez

Let G be a unimodular Lie group, X a compact manifold with boundary, and M the total space of a principal bundle G--> M-->X so that M is also a strongly pseudoconvex complex manifo…

Local equivalence problem for Levi flat hypersurfaces

Giuseppe Della Sala

In this paper we consider germs of smooth Levi flat hypersurfaces, under the following notion of local equivalence: S_1 ~ S_2 if their one-sided neighborhoods admit a biholomorphis…

Non-embeddability of certain classes of Levi flat manifolds

Giuseppe Della Sala

On the basis of a result of Barrett, we show that members of certain classes of abstract Levi flat manifolds with boundary, whose Levi foliation contains a compact leaf with contra…
