Grothendieck Groups of Complexes with Null-homotopies
نویسنده
چکیده
This paper is an addendum to [FH]. We reprove the main theorem of that paper by using Grothendieck groups of modules over certain DGAs. While the changes to the argument in [FH] are largely cosmetic, our approach shortens the proof from 25 pages down to 10 and greatly clarifies the overall structure. The authors of [FH] describe their proof as both “tedious” and “cumbersome”, whereas the approach given here is neither of these.

Tensor Products and Homotopies for Ω-groupoids and Crossed Complexes∗
Crossed complexes have longstanding uses, explicit and implicit, in homotopy theory and the cohomology of groups. It is here shown that the category of crossed complexes over groupoids has a symmetric monoidal closed structure in which the internal Hom functor is built from morphisms of crossed complexes, nonabelian chain homotopies between them and similar higher homotopies. The tensor product...
متن کاملRIGID DUALIZING COMPLEXES
Let $X$ be a sufficiently nice scheme. We survey some recent progress on dualizing complexes. It turns out that a complex in $kinj X$ is dualizing if and only if tensor product with it induces an equivalence of categories from Murfet's new category $kmpr X$ to the category $kinj X$. In these terms, it becomes interesting to wonder how to glue such equivalences.
متن کاملHomological Interpretation of Extensions and Biextensions of Complexes
Let T be a topos. Let Ki = [Ai ui → Bi] (for i = 1, 2, 3) be a complex of commutative groups of T with Ai in degree 1 and Bi in degree 0. We define the geometrical notions of extension of K1 by K3 and of biextension of (K1, K2) by K3. These two notions generalize to complexes with two entries the classical notions of extension and biextension of commutative groups of T. We then apply the geomet...
متن کاملOn the Functoriality of Cohomology of Categories
In this paper we show that the Baues-Wirsching complex used to define cohomology of categories is a 2-functor from a certain 2-category of natural systems of abelian groups to the 2-category of chain complexes, chain homomorphism and relative homotopy classes of chain homotopies. As a consequence we derive (co)localization theorems for this cohomology.
متن کاملNormalisation for the Fundamental Crossed Complex of a Simplicial Set
Crossed complexes are shown to have an algebra sufficiently rich to model the geometric inductive definition of simplices, and so to give a purely algebraic proof of the Homotopy Addition Lemma (HAL) for the boundary of a simplex. This leads to the fundamental crossed complex of a simplicial set. The main result is a normalisation theorem for this fundamental crossed complex, analogous to the u...
