Null-quadrics of codimension 4 in ℂ7

  • E. G. Anisova


In this paper we study the automorphisms of nondegenerate quadrics of type (4, 3). In particular, we classify the so-called null-quadrics (we prove that there are exactly two null-quadrics up to equivalence), and find their automorphism groups.

Key words

real analytic CR-manifold tangent quadric automorphism group holomorphic automorphism null-quadric
