Real Hypersurfaces in Complex Two-Plane Grassmannians

  • Jürgen Berndt
  • Young Jin Suh


 The complex two-plane Grassmannian G2(C m+2 in equipped with both a Kähler and a quaternionic Kähler structure. By applying these two structures to the normal bundle of a real hypersurface M in G2(C m+2 one gets a one- and a three-dimensional distribution on M. We classify all real hypersurfaces M in G2C m+2 , m≥3, for which these two distributions are invariant under the shape operator of M.

Key words: Complex Grassmannians real hypersurfaces tubes shape operator Kähler structure quaternionic Kähler structure
