Abstract: In the development of differential K-theory, the Bismut-Cheeger eta form plays a central role. In this talk, I will present a modified model of the differential K-group, building on the smooth K-theory framework developed by Bunke and Schick. I will discuss its equivariant generalization and explore key properties, with a particular focus on the localization property. This will lead to a localization formula for the Bismut-Cheeger eta forms. This work is a collaboration with Xiaonan Ma.
