报告摘要: For constantly curved holomorphic 2-spheres of degree 6 in the complex Grassmannian G(2,5), the first associated curve of the Veronese curve in CP^4 is the only known example in the literature up to now. In this talk, new examples will be shown. Moreover, we will talk about the moduli space of such 2-spheres, which is a semialgebraic set of real dimension 2. The discussion is based on deep investigation of the projective geometry for holomorphic 2-spheres in the Fano 3-fold of degree 5. This is a joint work with Quo-Shin Chi and Yan Xu.
