Free Boundary Stable Minimal Hypersurfaces in Positively Curved 4-Manifolds

Differential Geometry 2026-01-15 v3

Abstract

We show that the combination of nonnegative 2-intermediate Ricci Curvature and strict positivity of scalar curvature forces rigidity of two-sided free boundary stable minimal hypersurface in a 4-manifold with bounded geometry and weakly convex boundary. This extends the method of Chodosh-Li-Stryker to free boundary minimal hypersurfaces in ambient manifolds with boundary.
