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.
Keywords: geometric $K$-homology; differential $K$-characters.
