A model structure on categories related to categories of complexes
arXiv:1205.6066
Abstract
We prove a theorem of Hinich type on existence of a model structure on a category related by an adjunction to the category of differential graded modules over a graded commutative ring.
15 pages, the article is simplified: instead of two possible gradings (over Z and over NxZ) only one is left - over Z. Likely, the theorem with NxZ-grading will not be ever used
