Nonnegative Ricci curvature, small linear diameter growth and finite generation of fundamental groups

C Sormani - Journal of Differential Geometry, 2000 - projecteuclid.org
In 1968, Milnor conjectured that a complete noncompact manifold, M", with nonnegative
Ricci curvature has a finitely generated fundamental group [11]. This was proven for a …

Isoperimetric problem and structure at infinity on Alexandrov spaces with nonnegative curvature

G Antonelli, M Pozzetta - arXiv preprint arXiv:2302.10091, 2023 - arxiv.org
In this paper we consider nonnegatively curved finite dimensional Alexandrov spaces such
that unit balls have volumes uniformly bounded from below away from zero. We study the …

On the geometry at infinity of manifolds with linear volume growth and nonnegative Ricci curvature

X Zhu - Transactions of the American Mathematical Society, 2025 - ams.org
We prove that an open noncollapsed manifold with nonnegative Ricci curvature and linear
volume growth always splits off a line at infinity. This completes the final step to prove the …

Ricci curvature and convergence of Lipschitz functions

S Honda - arXiv preprint arXiv:1005.1040, 2010 - arxiv.org
We give a definition of convergence of differential of Lipschitz functions with respect to
measured Gromov-Hausdorff topology. As their applications, we give a characterization of …

The codimension one homology of a complete manifold with nonnegative Ricci curvature

Z Shen, C Sormani - American Journal of Mathematics, 2001 - muse.jhu.edu
In this paper we prove that a complete noncompact manifold with nonnegative Ricci
curvature has a trivial codimension one homology unless it is a flat normal bundle over a …

[PDF][PDF] Comparison geometry for Ricci curvature

X Dai, G Wei - preprint, 2012 - math.ucsb.edu
A Ricci curvature bound is weaker than a sectional curvature bound but stronger than a
scalar curvature bound. Ricci curvature is also special that it occurs in the Einstein equation …

On the topology of manifolds with nonnegative Ricci curvature and linear volume growth

D Navarro, J Pan, X Zhu - arXiv preprint arXiv:2410.15488, 2024 - arxiv.org
Understanding the relationships between geometry and topology is a central theme in
Riemannian geometry. We establish two results on the fundamental groups of open …

The topology of open manifolds with nonnegative Ricci curvature

Z Shen, C Sormani - arXiv preprint math/0606774, 2006 - arxiv.org
We survey all results concerning the topology of complete noncompact Riemannian
manifolds with nonnegative Ricci curvature that have no additional conditions other than …
