Abstract

We show that equivariant tilting modules over equivariant algebras induce equivalences of derived factorization categories. As an application, we show that the derived category of a noncommutative resolution of a linear section of a Pfaffian variety is equivalent to the derived factorization category of a noncommutative gauged Landau-Ginzburg model (Λ,χ,w)Gm(\Lambda,\chi, w)^{\mathbb{G}_m}, where Λ\Lambda is a noncommutative resolution of the quotient singularity W/GSp(Q)W/\operatorname{GSp}(Q) arising from a certain representation WW of the symplectic similitude group GSp(Q)\operatorname{GSp}(Q) of a symplectic vector space QQ.
