Delocalized eta invariants of the signature operator on G-proper manifolds
Paolo Piazza, Hessel Posthuma, Yanli Song +1
Let be a connected, linear real reductive group and let be a cocompact -proper manifold without boundary. We define delocalized eta invariants associated to a -inve…
Higher orbital integrals, rho numbers and index theory
Paolo Piazza, Hessel Posthuma, Yanli Song +1
Let be a connected, linear real reductive group. We give sufficient conditions ensuring the well-definedness of the delocalized eta invariant associated to a Dirac…
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…
Positive scalar curvature on simply connected spin pseudomanifolds
Boris Botvinnik, Paolo Piazza, Jonathan Rosenberg
Let be an -dimensional Thom-Mather stratified space of depth . We denote by the singular locus and by the associated link. In this paper we study the problem o…
