Generalized Koszul resolution, by Satoshi Mochizuki and Akiyoshi Sannai
The main objective of this paper is generalizing a notion of Koszul resolutions
and characterizing modules which admits such a resolution. We turn out that for
a noetherian domain A and a coherent A module M, M has a two dimensional
generalized Koszul resolution if and only if M is a pure weight two modules in
the sense of [HM09]. As its applications, we are attacking the Gersten
conjecture for weight two case.
