@article{Jadczyk2010SomeCO, title={Some Comments on Projective Quadrics Subordinate to Pseudo-Hermitian Spaces}, author={A. Jadczyk}, journal={Advances in Applied Clifford Algebras}, year={2010}, volume={22}, pages={79-85} }

We study in some detail the structure of the projective quadric Q′ obtained by taking the quotient of the isotropic cone in a standard pseudo-hermitian space Hp,q with respect to the positive real numbers $${\mathbb R^{+}}$$ and, further, by taking the quotient $${\tilde Q = Q^\prime /U(1)}$$. The case of signature (1, 1) serves as an illustration. Q̃ is studied as a compactification of $${\mathbb R \times H_{p-1,q-1}}$$
