... rings and modules, the statements of which have no reference to the DG universe. For instance, a standard theorem says the following: Theorem 1.2 ([20, Corollary 1]) Let (R, m) → (S, n) be a flat local ring homomorphism, that is, a ring homomorphism making S into a flat R-module such that mS ⊆ n.
