Topping" ], "categories": [ "math.DG" ], "abstract": "We survey several problems concerning Riemannian manifolds with positive curvature of one form or another. We describe the PIC1 notion of positive curvature and argue that it is often the sharp notion of positive curvature to consider. Finally we explain how recent Ricci flow theory is particularly well adapted to solve these problems.", "revisions": [ { "version": "v1", "updated": "2023-09-01T17:27:20.000Z" } ], "analyses": { "subjects": [ "53E20", "53C20" ], "keywords": [ "positive curvature", "problems concerning riemannian manifolds", "ricci flow theory", "pic1 notion", "sharp notion" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
