Examples of manifolds of positive Ricci curvature with quadratically nonnegatively curved infinity and infinite topological type
Huihong Jiang, Yihu Yang
In this paper, we construct a complete n-dim Riemannian manifold with positive Ricci curvature, quadratically nonnegatively curved infinity and infinite topological type. This give…
