K1 of Exact Categories by Mirror Image Sequences
Published online by Cambridge University Press: 19 April 2012
Abstract
We establish a presentation for K1 of any small exact category P, based on the notion of “mirror image sequence,” originally introduced by Grayson in 1979; as part of the proof, we show that every element of K1(P) arises from a mirror image sequence. This provides an alternative to Nenashev's presentation in terms of “double short exact sequences.”
