Abstract: From Delzant polytopes, we can construct complex manifolds and their real forms, a natural question is, can we construct manifolds from simplicial polytopes? In this talk, we address this question, and we prove that we can construct smooth manifolds from simplicial polytopes. The key ingredient is the local Z_2 systems on polytopes, and we use our recent results on cones and subdivisions to prove the existence. This is joint work with Bohui Chen and Anmin Li.
