Abstract

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. is studied as a compactification of \({\mathbb R \times H_{p-1,q-1}}\)
