英文摘要 | In this paper, we mainly study the geometry of conformal minimal immersions of two-spheres in a complex grassmann manifold g(2,4). at first, we give a precise description of any non-+/- holomorphic harmonic 2-sphere in g(2,4) with the linearly full holomorphic maps psi(0): s (2) -> a",p(3) (called its directrix curve) and then, it is proved that such a conformal minimal immersion i center dot: s (2) -> g(2, 4) with constant curvature has constant kaahler angle. furthermore, i center dot is either v (1) ((3)) + v (3) ((3)) , which is totally geodesic, with constant gauss curvature 2/5 and constant kaahler angle given by t = 3/2 or v (3) ((3)) + v (2) ((3)) , which is totally real, but it is not totally geodesic, with constant gauss curvature 2/3, where v (0) ((3)) , v (1) ((3)) , v (2) ((3)) , v (3) ((3)) : s (2) -> a",p(3) is the veronese sequence. |
