Collapsing Ricci Limit Spaces with No Manifold Structure
Kai-Hsiang Wang (Northwestern University)
Abstract
It is known in the literature that a non-collapsing Ricci limit space admits a manifold structure on an open dense subset (J. Cheeger and T. H. Colding, '97). It has been an open question how regular can a collapsing Ricci limit space be (A. Naber, '20). In our joint work with Erik Hupp and Aaron Naber, we provide an example of collapsing Ricci limits that admit no manifold structure (nowhere Euclidean).
