Abstract We explain a fundamental additivity theorem for Euler characteristics and generalized trace maps in triangulated categories. The proof depends on a refined axiomatization of symmetric monoidal categories with a compatible triangulation. The refinement consists of several new axioms relating products and distinguished triangles. The axioms hold in the examples and shed light on generalized homology and cohomology theories. 
A remark on the additivity of traces in triangulated categories
The additivity of traces in certain tensor triangulated categories for endomorphisms of finite order of distinguished triangles is investigated. For the identity endomorphism this has been fully
Notes on Triangulated Categories
We give an elementary introduction to the theory of triangulated categories covering their axioms, homological algebra in triangulated categories, triangulated subcategories, and Verdier
Subcategory Classifications in Tensor Triangulated Categories
It is known that the thick tensor-ideal subcategories in a tensor triangulated cate- gory can be classified via its prime ideal spectrum. We use this to provide new proofs of two well-known
The Fundamental Group of a Morphism in a Triangulated Category
We introduce the fundamental group of a morphism in a triangulated category and show that the groupoid of distinguished triangles containing a given extension of objects from an abelian category is
The additivity of traces in monoidal derivators
Motivated by traces of matrices and Euler characteristics of topological spaces, we expect abstract traces in a symmetric monoidal category to be "additive". When the category is "stable" in some
Finite dimensional objects in distinguished triangles
We prove an additivity for evenly (oddly) finite dimensional objects in distinguished triangles in a triangulated monoidal category structured by an underlying model monoidal category. In particular,
Symmetric powers in stable homotopy categories
We construct Z-coefficient symmetric powers in a symmetric monoidal triangulated category, provided it is the homotopy category of a closed simplicial symmetric monoidal model category. Under certain
Axiomatic stable homotopy - a survey
We survey various approaches to axiomatic stable homotopy theory, with examples including derived categories, categories of (possibly equivariant or localized) spectra, and stable categories of
Motives over simplicial schemes
In this paper we define the triangulated category of motives over a simplicial scheme. The morphisms between the Tate objects in this category compute the motivic cohomology of the underlying scheme.
The linearity of fixed point invariants
We prove two general decomposition theorems for fixed-point invariants: one for the Lefschetz number and one for the Reidemeister trace. These theorems imply the familiar additivity results for these
