Regularity of Cohomogeneity two equivariant isotopy minimization problems and minimal hypersurfaces with large first Betti number on spheres
Dongyeong Ko
We prove the regularity of cohomogeneity two equivariant isotopy minimization problems. Based on this, we develop cohomogeneity two equivariant min-max theory for minimal hypersurf…

Scalar curvature comparison and rigidity of -dimensional weakly convex domains
Dongyeong Ko, Xuan Yao
For a compact Riemannian -manifold with mean convex boundary which is diffeomorphic to a weakly convex compact domain in , we prove that if scalar c…
