This appendix recalls definitions and fundamental properties of derived factorization categories. See [Pos, BFK1, BDFIK, Hir1, Hir3] for more details.
where W in the left LG model denotes f ∗W by abuse of notation, and the functor (A.A) defines the right derived functor
The following shows an equivariant and factorization version of a tilting equivalence.
Lemma A.6 ([BFK1, Proposition 3.20][1]). Assume that the sections s and t ∗ are regular. Then there are isomorphisms
