报告题目： Holomorphic sectional curvature and the structure of projective Kaehler manifolds

摘要：

I will present recent results on the consequences of semi-definite holomorphic sectional curvature for the geometric structure of projective Kaehler manifolds. In the semi-positive case, the focus is on the existence of rational curves. In the semi-negative case, the focus is on semi-positivity of the canonical line bundle and splitting theorems. This talk covers various joint works with S. Lu, B. Wong and F. Zheng.
