The CR Ahlfors derivative and a new invariant for spherically equivalent CR maps
Bernhard Lamel, Duong Ngoc Son
We study a CR analogue of the Ahlfors derivative for conformal immersions of Stowe [23] that generalizes the CR Schwarzian derivative studied earlier by the second-named author [21…
On the Chern-Moser-Weyl tensor of real hypersurfaces
Michael Reiter, Duong Ngoc Son
We derive an explicit formula for the well-known Chern-Moser-Weyl tensor for nondegenerate real hypersurfaces in complex space in terms of their defining functions. The formula is…
Semi-isometric CR immersions of CR manifolds into Kähler manifolds and applications
Duong Ngoc Son
We study the second fundamental form of semi-isometric CR immersions from strictly pseudoconvex CR manifolds into Kähler manifolds. As an application, we give a precise condition f…
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…
