Abstract
We define a group of relative differential
K-characters associated with a smooth map between two smooth
compact manifolds. We show that this group fits into a short
exact sequence as in the non-relative case. Some secondary
geometric invariants are expressed in this theory.
Key words:
geometric K-homology; differential K-characters.
