Av-theory of categories

Research output: Contribution to journalArticlepeer-review

Abstract

Quillen has constructed a A-theory K*C for nice categories, one of which is the category of projective A-modules. We construct a theory KV* C for the nice categories parametrized by rings. When applied to projective modules we recover the Karoubi-Villamayor A-theory KV*(R). As an application, we show that the Cartan map from K*(R) to G*(R) factors through the groups KVJ*(R). We also compute KV* for the categories of faithful projectives and Azumaya algebras, generalizing results of Bass.
