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?)
