Costello's pushforward formula: errata and generalization

Algebraic Geometry 2021-03-19 v1

Abstract

K. Costello's Pushforward Formula is not correct as stated. We verify it holds under an assumption of properness or of a weaker notion we call "purity." We then check many papers that used this formula to make sure it holds in their context.
