Holomorphic 2-spheres in a complex Grassmann manifold G (2,5)
摘要
Abstract
We study the linearly full holomorphic 2-spheres in a complex Grassmann manifold G(2, 5) by using harmonic sequence and moving frames. We construct some examples of homogeneous holomorphic 2-spheres in G(2, 5 ) by applying the irreducible unitary representations of SU (2). Then, we determine all linearly full degenerate holomorphic 2-spheres with constant Gaussian curvatures of 2/3 and 4/3, up to U (5) equivalence. Moreover, we prove that all nondegenerate holomorphic 2-spheres with constant Gaussian curvature of 4/3 must be U(5 ) equivalent under some conditions.关键词
