Quadrics of codimension 4 in ℂ7 and their automorphisms

  • E. G. Anisova


Automorphisms of nondegenerate (4, 3)-quadrics are studied. We classify quadrics of this kind with nonlinear automorphisms and find the dimensions of their groups of automorphisms.

Key words

tangent nondegenerate quadric null-quadric Hermitian matrices characteristic polynomial of a quadric
