Identification of the sheaf-theoretic and KZ functors

From papers

Let ccalC0ccalC_0 and ccalB0ccalB_0 be the source and target categories, let ccalM:ccalC0ccalB0ccalM:ccalC_0\longrightarrow ccalB_0 be the sheaf-theoretic functor, and let cPhicPhi_*, cKZcKZ, and cPsicPsi^* be the functors appearing in the paper. Functor-identification conjecture. The functors

\calM:\calC0\calB0\calM:\calC_0\longrightarrow \calB_0

and

Ψ\KZΦ:\calC0\calB0\Psi^*\circ \KZ\circ \Phi_*:\calC_0\longrightarrow \calB_0

are isomorphic.

This assertion identifies the sheaf-theoretic functor with the composite obtained from the geometric equivalence and the KZ functor. The supplied context does not state whether the assertion is proved, so its status is left open.
