The Characteristic Cohomology Class of A

  title={The Characteristic Cohomology Class of A},
  author={H.-J Baues and Fernando Muro},
Introduction This is a collection of four papers on the foundation of triangulated categories in the context of groupoid-enriched categories, termed track categories, and characteristic cohomology classes. As a main result it is shown that given an additive category A with a translation functor t : A → A and a class in translation cohomology ∇ ∈ H 3 (A, t… CONTINUE READING
