From the first line it appears to about **D-modules on stacks**.

The second topic is an attempt to construct a "duality" (called F) for derived category of (quasicoherent) D-modules on `Bun_G` (the space/stack of G-bundles). The problem is to find a "reverse Langlands transform" (?) by defining a suitable scalar product on those.

In the middle a single question  appears, "What is the Eisenstein fuctor?" (indeed, what is it?)
