Boundary Conditions for Scalar Curvature [OWP-2021-01] (Mathematisches Forschungsinstitut Oberwolfach, 2021-01-04)Based on the Atiyah-Patodi-Singer index formula, we construct an obstruction to positive scalar curvature metrics with mean convex boundaries on spin manifolds of infinite $K$-area. We also characterize the extremal case. ...
