η-Invariant and Flat Vector Bundles
Xiaonan;MA;Weiping;ZHANG
Abstract:
We present an alternate definition of the mod Z component of the Atiyah-Patodi-Singer η invariant associated to（not necessary unitary ）flat vector bundles,which identifies explicitly its realandimaginary parts.This is done by combining a deformation of flatconnections introduced in a previous paper with the analytic continuation procedure appearing in the original article of Atiyah Patodi and Singer.[著者文摘]
Key words:
Flat vector bundle，η-Invariant ρ-Invariant
