Differential K-theory is a new research field in the 21st century which is motivated by the study of superstring theory in theoretical physics. It is the differential extension of the topological K-theory and can be regarded as the real analogue of the arithmetic
K-theory in Arakelov geometry, which is the arithmetic extension of the K-theory introduced by Grothendieck. In this talk, we will discuss the properties of differential K-theory by comparing them with corresponding properties of arithmetic K-theory and use them to derive some new geometric results. In particular, we will obtain the localization
formulas for eta invariants and eta forms from the localizations in differential K-theory.
