It is well-known, due to Schoen-Yau, that any closed stable minimal hypersurface of $Y$ also admits a psc-metric. We establish an analogous result for stable minimal hypersurfaces with free boundary. Furthermore, we combine this result with tools from geometric measure theory and conformal geometry to study psc-bordism. For instance, assume $(Y_0,g_0)$ and $(Y_1,g_1)$ are closed psc-manifolds equipped with stable minimal hypersurfaces $X_0 \\subset Y_0$ and $X_1\\subset Y_1$. Under natural topological conditions, we show that a psc-bordism $(Z,\\bar g) : (Y_0,g_0)\\rightsquigarrow (Y_1,g_1)$ gives rise to a psc-bordism between $X_0$ and $X_1$ equipped with the psc-metrics given by the Schoen-Yau construction.", "revisions": [ { "version": "v1", "updated": "2016-09-28T22:24:12.000Z" } ], "analyses": { "subjects": [ "53C27", "57R65", "58J05", "58J50" ], "keywords": [ "positive scalar curvature metrics", "geometric measure theory", "psc-bordism", "compact riemannian manifold", "conformal geometry" ], "note": { "typesetting": "TeX", "pages": 27, "language": "en", "license": "arXiv", "status": "editable" } } }
