【 摘 要 】

A class of logarithmic-functors is constructed which allow additive invariants on categories to be formulated as functors on A(infinity) 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. (C) 2017 Elsevier B.V. All rights reserved.
