摘 要：In this talk, we introduce a new approach to studying constantly curved holomorphic 2-spheres of degree 6 in the complex Grassmannian G(2,5), based on an analysis of sextic rational curves in the quintic del Pezzo 3-fold $V_5$. A key result establishes that a sextic rational curve in $V_5$ admits a Galois cover in $P^3$ with the Galois group a subgroup of the projective binary octahedral group. This connection also naturally leads to the question of how the moduli space of sextic rational curves in $V_5$ can be characterized via their Galois covers in $P^3$. The classification of sextic curves in $V_5$ that admit rational Galois covers in $P^3$ will be shown. The work is joint with Professor Quo-Shin Chi and Yan Xu.
