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.
