Quasi-Isomorphisms of Commutative DG Rings and Divided Power Structures
Quasi-Isomorphisms of Commutative DG Rings and Divided Power Structures
Abstract We prove that a quasi-isomorphism f : A → B between commutative DGrings, where B admits a divided power structure, can be factored as f = f ̃ ◦ e, wheree : A → B ̃ is a split injective quasi-isomorphism, and f ̃ : B ̃ → B …
