abstract

We consider an area-minimizing integral current $T$ of codimension higher than 1 ins a smooth Riemannian manifold $\Sigma$. We prove that $T$ has a unique tangent cone, which is a superposition of planes, at $\mathcal{H}^{m-2}$-a.e. point in its support. In combination with works of the first and third authors, we conclude that the singular set of $T$ is countably $(m-2)$-rectifiable.

  1. Area-minimizing submanifolds are not generically smooth, except for geodesics, minimal surfaces, and minimal hypersurfaces

    math.DG 2026-07 accept novelty 8.0 of 10

    For d≥3 and c≥2, open sets of metrics force every mod-2 area-minimizer to have singular set of Hausdorff dimension at least d−3; the Veronese RP2 cone is mod-2 minimizing.

  2. On the Nature of Stationary Integral Varifolds near Multiplicity 2 Planes

    math.DG 2025-07 accept novelty 8.0 of 10

    Near a multiplicity-two plane, a stationary integral varifold with a topological separation condition in flat low-density cylinders is a generalized C^{1,alpha} two-valued graph with unique tangent cones.

  3. Generic regularity for minimizing hypersurfaces in dimension 11

    math.DG 2025-06 conditional novelty 8.0 of 10

    Area-minimizing hypersurfaces are generically smooth in ambient dimension 11 after a C-infinity-small perturbation of the boundary or metric, and in dimensions 12 and up the singular set has dimension at most n-10-epsilon_n.

  4. Analysis of singularities of area-minimizing currents, Part III: branch points of planar frequency $\neq$ 2, higher order asymptotics, and the local topology

    math.DG 2026-07 conditional novelty 7.0 of 10

    At almost every branch point with planar frequency ≠ 2, an area-minimizing current has a unique algebraic tangent blow-up, a higher-order expansion with remainder bounds, a locally rectifiable branch-set decomposition...
