Reducible Conformal Minimal Immersions with Constant Curvature from S^(2)to Q_(6)
《Journal of Mathematical Research with Applications》2024年第6期807-824,共18页Xiaoxiang JIAO Mingyue LI 
Supported by the National Natural Science Foundation of China(Grant No.12371055)。
Using the harmonic map theory,we study the geometry of conformal minimal twospheres immersed in Q_(6),or a real Grassmannian manifold G(2,8;R)equivalently.Then we classify the linearly full reducible conformal minimal...
