Attaching faces of positive scalar curvature manifolds with corners

Differential Geometry 2024-02-20 v2

Abstract

We prove a novel desingularization theorem, that allows to smoothly attach two given manifolds with corners by suitably gluing a pair of isometric faces, with control on both the scalar curvature of the resulting space and the mean curvature of its boundary.
