On K1 of a Waldhausen Category
We give a simple representation of all elements in K1 of a Waldhausen category and prove relations between these representatives which hold in K1.
متن کاملRelative Homological Algebra, Waldhausen K-theory, and Quasi-frobenius Conditions
We study the question of the existence of a Waldhausen category on any (relative) abelian category in which the contractible objects are the (relatively) projective objects. The associated K-theory groups are “stable algebraic G-theory,” which in degree zero form a certain stable representation group. We prove both some existence and nonexistence results about such Waldhausen category structure...
متن کاملK-theory of a Waldhausen Category as a Symmetric Spectrum
If C is a Waldhausen category (i.e., a “category with cofibrations and weak equivalences”), it is known that one can define its K-theory K(C) as a connective symmetric Ω-spectrum. The goal of these notes is to explain the construction in such a way that it can be not only understood, but also (hopefully) remembered by a non-expert. We do not claim that our exposition shows the process by which ...
متن کاملThe 1-type of a Waldhausen K-theory Spectrum
We give a small functorial algebraic model for the 2-stage Postnikov section of the K-theory spectrum of a Waldhausen category and use our presentation to describe the multiplicative structure with respect to biexact functors.
متن کاملMaltsiniotis’s First Conjecture for K1
We show that K1(E) of an exact category E agrees with K1(DE) of the associated triangulated derivator DE. More generally we show that K1(W) of a Waldhausen category W with cylinders and a saturated class of weak equivalences agrees with K1(DW) of the associated right pointed derivator DW. Introduction For a long time there was an interest in defining a nice K-theory for triangulated categories ...
