Fourier transform

used in the proof of the geometric Langlands program

the Fourier transform sends complexes of sheaves on the total space of E to complexes of sheaves on the total space of the dual bundle E*

I only accepted Manjul Bhargava's solution because Mumford's proof of the GFGA theorem appeared in his answer to the problem set by me.
