Sara Azzali, Charlotte Wahl
We relate the spectral flow to the index for paths of selfadjoint Breuer-Fredholm operators affiliated to a semifinite von Neumann algebra, generalizing results of Robbin-Salamon a…

The Atiyah-Patodi-Singer index theorem for Dirac operators over C*-algebras
Charlotte Wahl
We prove an Atiyah-Patodi-Singer index theorem for Dirac operators twisted by C*-vector bundles. We use it to derive a general product formula for eta-forms and to define and study…
