Degree of constantly curved holomorphic 2-spheres in the complex Grassmannians

In this talk, we discuss the degree of the linearly full constantly curved holomorphic 2-spheres in the complex Grassmannians G(2,n+2;C). We show that the lower bound of the degree is n, and the upper bound is 2n for n=2,3.
