What os the meaning of `a reverse Langlands transform` to which Drinfeld [seems to refer](https://mathoverflow.net/questions/2464/what-is-drinfelds-manuscript-best-dream-in-russian-about)?



Reverse Langlands transform
My guess is that, traditionally, the Geometric Langlands program seems to be looking for a functor from D\_{coh}(Loc,O)\to D\_{coh}(^L Bun,D), that is, from the derived category on the space of local systems to the derived category of D-modules on the space of bundles for the Langlands dual. So, by reverse Langlands transformation, he might be asking for a functor in the other direction, to try to establish the equivalence.
