Abstract:

In this article, it is proved that there doesn't exist any nonsingular holomorphic sphere in complex Grassmann manifold G(2, 5) with constant curvature k=4/7, 1/2, 4/9. Thus, from [7] it follows that if φ: S2G(2, 5) is a nonsingular holomorphic curve with constant curvature K, then, K=4, 2, 4/3, 1 or  4/5.

Key words: Gauss curvature, holomorphic curve, complex Grassmann manifold
