摘要:In this talk, we will discuss how to study the constantly curved minimal 2-spheres in complex hyperquadrics Q^n and G(2,5) from the viewpoint of linear section. For Q^n, the moduli space of these kind of spheres is investigated using the singular-value decomposition theory of complex matrices. For G(2,5), we will focus on the constantly curved holomorphic 2-spheres of degree 6, some nonexistence results are obtained.
