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 $l>0$ in ${\mathbb{C}}^n$, $n\ge 3$, to the local model for the tube over the null cone of a symmetric form in $\mathbb{C}^{n+…
