內(nèi)容介紹:In this talk, we consider mean curvature positivity of holomorphic vector bundle. We will show that the mean curvature positivity is equivalent to the HN-positivity. As its applications, we establish the correspondence between rational connectedness in algebraic geometry and mean curvature positivity in differential geometry. We also introduce our recent work on the rational connectedness of compact K?hler manifolds which extends Yau's conjecture to the quasi-positive case. These works are joint with Chao Li, Shiyu Zhang and Chuanjing Zhang.
