WebMar 22, 2024 · Abstract. We give the first examples of collapsing Ricci limit spaces on which the Hausdorff dimension of the singular set exceeds that of the regular set; moreover, the Hausdorff dimension of these spaces can be non-integers. This answers a question of Cheeger-Colding [ CC00a, Page 15] about collapsing Ricci limit spaces. WebFeb 8, 2024 · For instance, the theory of Alexandrov spaces is developed to study limit spaces with sectional curvature bounded from below, and similar situations apply to spaces with bounded Ricci curvature via Cheeger-Colding-Naber Theory. However, the corresponding results on scalar curvature are still far from being understood.
