Corrections to Superfiltered A-infinity deformations of the exterior algebra, and local mirror symmetry
In Section 5.1, the expressions given for the differential and cup product on the Hochschild cochain complex are really expressions for the μ¹ and μ² operations. In order to call them the differential and cup product (for example, in order for the product to be associative after passing to cohomology), they should be twisted by the usual signs as given in (3).
In the second paragraph of the proof of Lemma 6.10, the γ₋ should be γ₊.
