We show uniqueness of cylindrical blowups for mean curvature flow in all dimension and all codimension. Cylindrical singularities are known to be the most important; they are the most prevalent in any codimension. Mean curvature flow in higher codimension is a nonlinear parabolic system where many of the methods used for hypersurfaces do not apply and uniqueness of cylindrical blowups remained a major open problem. Our results imply regularity of the singular set for the system.

  1. Codimension Bounds and Rigidity of Ancient Mean Curvature Flows by the Tangent Flow at $-\infty$

    math.DG 2019-09 conditional novelty 7.0 of 10

    Ancient mean curvature flows that converge rapidly to a compact self-shrinker at time minus infinity must have the same codimension as the shrinker, and if the convergence is super-exponential the flow equals the shrinker.

  2. Construction of High Codimension Ancient Mean Curvature Flows

    math.DG 2019-08 conditional novelty 2.0 of 10

    The paper constructs high-codimension ancient curve shortening flows, but the abstract and Remark 1.3 state the construction was earlier discovered in AAAW13.
