The generic regularity hypothesis for least-area hypersurfaces

Let Mn+1M^{n+1} be a closed smooth manifold, let Hn(M;Z)H_n(M;\mathbb{Z}) denote its codimension-one homology group, and let a representative of a homology class mean a smooth hypersurface in that class. Generic regularity hypothesis. There is a Baire generic set of metrics G\mathcal{G} such that, for every gGg\in\mathcal{G} and every σHn(M;Z)\sigma\in H_n(M;\mathbb{Z}), there is a smooth representative Σσ\Sigma\in\sigma of least area. This hypothesis would address the singularities of area-minimizing hypersurfaces in high dimensions and provide a route to applying minimal-surface methods more broadly. The source says the conjecture has appeared in various forms since at least the 1980s and gives no resolution evidence.
