The classification of CR maps from hyperquadrics into tubes over null cones of symmetric forms
Nguyen Gia Hien, Michael Reiter, Duong Ngoc Son
We classify CR maps from the hyperquadric of signature in , , to the local model for the tube over the null cone of a symmetric form in $\mathbb{C}^{n+…

On CR maps between hyperquadrics and Winkelmann hypersurfaces
Michael Reiter, Duong Ngoc Son
In this paper, we study CR maps between hyperquadrics and Winkelmann hypersurfaces. Based on a previous study on the CR Ahlfors derivative of Lamel-Son and a recent result of Huang…
