3-manifolds researchers

People whose work on 3-manifolds is a good place to start, in alphabetical order. No one left off is slighted: it is a way in, not a ranking.

• John Morgan
• Miles Simon

• RBRichard BamlerBuilt a compactness and structure theory for Ricci flow in all dimensions; with Bruce Kleiner, proved Perelman's conjecture on flow through singularities.
• SBSimon BrendleWith Schoen proved the differentiable sphere theorem; also solved the Lawson conjecture and classified three-dimensional Ricci flow singularity models.
• HCHuai-Dong CaoProved long-time existence of the Kähler–Ricci flow in 1985, found Harnack estimates for it, and studied the geometry and stability of Ricci solitons.
• PCPak-Yeung ChanStudies Ricci solitons and the singularities they model: volume growth, curvature decay, unique tangent flows and Kähler flying wings.
• KCKyeongsu ChoiStudies singularities of curvature flows: ancient solutions, the mean convex neighbourhood conjecture in R^3, and roundness under Gauss curvature flow.
• RHRobert HaslhoferProved the mean convex neighbourhood conjecture at necks with collaborators, reworked mean convex flows with Kleiner, defined weak Ricci flow with Naber.
• MLMan-Chun LeeBuilds Ricci flows from rough or pinched data: Hamilton's pinching conjecture, collapsing Kähler–Ricci flows and scalar curvature rigidity.
• YLYu LiClassified Kähler Ricci shrinker surfaces with Bing Wang and, with Hanbing Fang, built a Gromov–Hausdorff structure theory for Ricci flow limits.
• NŠNataša ŠešumClassified compact ancient solutions of Ricci flow and curve shortening with Daskalopoulos, Hamilton, Angenent and Brendle; shared the 2023 Satter Prize.
• GTGang TianIntroduced K-stability for Kähler–Einstein metrics, wrote a detailed proof of the Poincaré conjecture with Morgan, and studied Kähler–Ricci flow.
• PTPeter ToppingWrote Lectures on the Ricci Flow, studied Ricci flow from rough surfaces, and with Man-Chun Lee built the flow behind Hamilton's pinching conjecture.
