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…
The CR umbilical locus of a real ellipsoid in
Duong Ngoc Son
This paper concerns the CR umbilical locus of a real ellipsoid in , the set of points at which the ellipsoid can be osculated by a biholomorphic image of the sphere u…
An upper bound for the first positive eigenvalue of the Kohn Laplacian on Reinhardt real hypersurfaces
Gian Maria Dall'Ara, Duong Ngoc Son
A real hypersurface in is said to be Reinhardt if it is invariant under the standard -action on . Its CR geometry can be described in ter…
On CR maps from the sphere into the tube over the future light cone
Michael Reiter, Duong Ngoc Son
We determine all local smooth or formal CR maps from the unit sphere into the tube $\mathcal{T}:= \mathcal{C} \times i\mathbb{R}^3 \subset \mathb…
Eigenvalues of the Kohn Laplacian and deformations of pseudohermitian structures on CR manifolds
Amine Aribi, Duong Ngoc Son
We study the eigenvalues of the Kohn Laplacian on a closed embedded strictly pseudoconvex CR manifold as functionals on the set of positive oriented pseudohermitian structures $\ma…
