WebJul 15, 2012 · Here by higher pushforward I mean the right derived functor of the pushforward functor. I'm wondering if higher pushforward of open immersions between schemes have some geometric meaning. For a proper flat map, the higher pushforward is like a sheaf which contains information of the cohomology of the fibers.
WebThere are issues with this derived de nition: how does one compose left and right derived functors? I can’t resolve them here. We need that there is a derived pushforward, and consequently we get a long exact sequence in cohomology. See [2, Section 1.5]. Example 2.3.

WebJul 20, 2024 · We give a new proof of Kollár’s conjecture on the derived pushforward of the dualizing sheaf twisted by a variation of Hodge structure. This conjecture has been settled by M. Saito via the theory of mixed Hodge modules and has various applications in the investigation of Albanese maps. Our technique is L^2 theoretic which gives concrete ...

The real reason to use derived category is that there are higher direct images.
