Abstract

In this paper, we give a local rigid characterization of all homogeneous holomorphic two-spheres in a complex Grassmann manifold G(2, N). Let κ denote the new global invariant defined in terms of the square norm of (1, 0) part of the second-order covariant differential of the first ∂ -transform for a holomorphic curve in G(2, N). It is proved that a linearly full non-degenerate holomorphic curve of constant curvature and constant square norm of the second fundamental form in G(2, N) with κ= 0 must be homogeneous.
