On the number of affine equivalence classes of spherical tube hypersurfaces

Isaev, Alexander


We consider Levi non-degenerate tube hypersurfaces in Cn+1 that are (k, n - k)-spherical, i. e. locally CR-equivalent to the hyperquadric with Levi form of signature (k, n - k), with n ≤ 2k. We show that the number of affine equivalence classes of such
