Lickorish type construction of manifolds over simple polytopes
Zhi Lü, Wei Wang, Li Yu
This paper is a survey on the Lickorish type construction of some kind of closed manifolds over simple convex polytopes. Inspired by Lickorish's theorem, we propose a method to des…

Small Cover and Halperin-Carlsson Conjecture -II
Li Yu
For a small cover Q^n and any principal (Z_2)^m-bundle M^n over Q^n, it was shown in a previous work of the author that the total sum of Z_2-Betti numbers of M^n is at least 2^m. I…
