摘要：

In this paper we completely classify the linearly full homogeneous holomorphic two-spheres in the complex Grassmann manifolds G(2, N) and G(3, N). We also obtain the Gauss equation for the holomorphic immersions from a Riemann surface into G(k, N). By using which, we give explicit expressions of the Gaussian curvature and the square of the length of the second fundamental form of these homogeneous holomorphic two-spheres in G(2, N) and G(3, N).
