Structure of Torus Fibration Under the First Betti Number Restriction
Xin Peng, Bing Wang, Zhenjian Wang
We study torus bundles with affine structure groups. First, we establish a rigidity result under constraints on the first Betti numbers: If $ \text{b}_{1}(M)-\text{b}_{1}(N)=\dim M…

Curvature at the infinity of asymptotically flat Einstein manifold
Bing Wang, Hao Yin
In this paper, we construct coordinates at the infinity of an asymptotically flat end of a Ricci-flat manifold as long as the norm of the curvature is finite i…
