In this paper, we continue the study of positive scalar curvature (psc) metrics on a depth-1 Thom-Mather stratified space Σ with singular stratum (a closed manifold of positive codimension) and associated link equal to , a smooth compact manifold. We briefly call such spaces manifolds with -fibered...
