Characterization on projective submanifolds of codimensions 2 and 3
Ping Li, Fangyang Zheng
In this article we give a necessary and sufficient condition to characterize projective submanifolds in with codimensions 2 and 3. The conditions involve the Chern…

Combinatorial identities and Chern numbers of complex flag manifolds
Ping Li, Wenjing Zhao
We present in this article a family of new combinatorial identities via purely differential/complex geometry methods, which include as a speical case a unified and explicit formula…
