Correction to: “Regular differentials and equidimensional scheme-maps”

TL;DR: In this article, a sign error involving a sign in the principal result of the Leray spectral sequence was corrected, while comparing the conventions used for Leray sequences in [C] with our conventions, and comparing [C, p. 173, Cor. 3.6] with their principal result (viz., [LS, p 118,Thm. (4.1)]).

Abstract: We correct a sign error in the principal result of our paper [LS]. We noticed an error involving a sign in our paper [LS] while comparing the conventions used for Leray spectral sequences in [C] with our conventions, and comparing [C, p. 173,Cor. 3.6.6] with our principal result (viz., [LS, p. 118,Thm. (4.1)]). All numerical references (e.g. (3.2.3)) and page numbers are to [LS] except for (3.2.3)′ below. Diagrams and maps in this note are labelled in a non-numerical manner (e.g. (τ)) to avoid confusion. The exception to this is again (3.2.3)′. Proposition (3.3.1) on p. 114 is incorrectly stated: the right side of the asserted equality needs to be multiplied by a factor of (−1)nd. Equivalently, the equality should read
