Kaledin formality in families
WebbWe provide proper foundations and proofs for the main results of Kaledin (2007) [Ka]. The results include a flat base change for formality and behavior of formality in flat families of A(∞) and DG algebras. WebbWe prove some results on formality for families of DG algebras; in particular, we prove that formality is stable under specialization. The results are more-or-less known, but it seems that there are no published proofs.
