Abstract (English)

Let M be a closed connected oriented odd-dimensional manifold. The Atiyah–Patodi–Singer-ρ-invariant assigns to a unitary representation α of the fundamental group a real number ρ(M,α). In other words, given M and a natural number k, we can view the ρ-invariant as a function defined on the variety Rₖ(π₁(M)) of k-dimensional unitary representations of the fundamental group of M. Cheeger and Gromov ...


Translation of the abstract (German)

Sei M eine geschlossene zusammenhängende orientierte Mannigfaltigkeit ungerader Dimension. Die Atiyah–Patodi–Singer ρ-Invariante ordnet einer unitären Darstellung α der Fundamentalgruppe eine reelle Zahl ρ(M,α) zu. Anders gesagt, für festes M und k können wir die ρ-Invariante als Funktion betrachten, welche auf der Varietät Rₖ(π₁(M)) der k-dimensionalen unitären Darstellungen der ...
