Title

On Smooth Projective Manifolds with Topological Circle Bundle Structures

One of Yau’s conjectures (ICCM 2013) says that canonically polarized complex projective manifolds do not admit nontrivial topological $S^1$-actions. In this talk, I will give a discussion on projective manifolds with topological $S^1$-actions, and show that canonically polarized complex projective manifolds do not admit free topological $S^1$-actions if their Albanese varieties are simple.

Positivity of the Tangent Bundle of Smooth Projective Surfaces
AbstractConsider a non-uniruled smooth projective surface S. We establish that the tangent bundle T_S is pseudo-effective if and only if the canonical divisor K_S is nef, and the second Chern class c_2(S) vanishes. Additionally, I will discuss the blow-up of a non-rational ruled surface with a pseudo-effective tangent bundle. This talk is based on a collaborative project with Yongnam Lee and Gu...
