Positive Scalar Curvature on Spin Pseudomanifolds: the Fundamental Group and Secondary Invariants
Boris Botvinnik, Paolo Piazza, Jonathan Rosenberg
In this paper we continue the study of positive scalar curvature (psc) metrics on a depth-1 Thom-Mather stratified space with singular stratum (a closed manifold of posi…

Signatures of Witt spaces with boundary
Paolo Piazza, Boris Vertman
Let M be a compact smoothly stratified pseudomanifold with boundary, satisfying the Witt assumption. In this paper we introduce the de Rham signature and the Hodge signature of M,…

A note on higher Todd genera of complex manifolds
Francesco Bei, Paolo Piazza
Let be a compact complex manifold. In this paper we give a simple proof of the bimeromorphic invariance of the higher Todd genera of , a result first proved implicitly by Br…
