Almost mathematics of pointed symmetric monoidal model categories by Smith ideal theory

Abstract

This article is a generalization of a result in Quillen's note ``Module theory over non-unital rings'' giving a one-to-one correspondence between bilocalization of abelian categories of modules and idempotent ideals of the base ring. Faltings; Gabber and Ramero established almost mathematics, the same as Quillen's bilocalization of a category of modules by nil modules. In this paper, by using the theory of Smith ideals mentioned in Hovey and Smith, we consider almost mathematics of symmetric monoidal pointed model categories. We prove a weak analogue of the one-to-one correspondence in Quillen.
