Fibrations, the First Betti Number, and Almost Nonnegative Ricci Curvature
Hongzhi Huang, Xian-Tao Huang, Jikang Wang +1
In this paper, we prove fibration theorems for manifolds with almost nonnegative Ricci curvature and certain extra regularity assumptions. We show that a closed -manifold sa…

On the local topology of non-collapsed Ricci bounded limit spaces
Song Sun, Jikang Wang, Junsheng Zhang
We show that for a pointed Gromov-Hausdorff limit of non-collapsed Riemannian manifolds with bounded Ricci curvature, the local of the regular loci vanishes. We also discuss…
