Topological obstructions to geometric positivity and negativity on Calabi-Yau manifolds
Ping Li
We study whether the topology underlying a Calabi-Yau manifold can support natural geometric positivity or negativity structures. In even complex dimension (assuming $b_…

Compactification of homology cells, Fujita's conjectures and the complex projective space
Ping Li, Thomas Peternell
We show that a compact Kähler manifold containing a smooth connected divisor such that is a homology cell, e.g., contractible, must be projective space with…
