Abstract

A class of logarithmic-functors is constructed which allow additive invariants on categories to be formulated as functors on categories. Characters of such logarithmic representations provide a functorial structure for exotic torsions and include Chern characters, Reidemeister torsion and topological signatures. A number of examples are given.
