It is a real algebraic proper submersion, but not holomorphic. WebDerived category D(A). Motivation: many natural functors on sheaves are not exact in general. However, exactness is preserved on certain subcategories, i.e. the subcategory …

Webkernels of triangulated functors between derived categories of sheaves on schemes. In this talk, I will show a new uniqueness result for lifts of triangulated functors coming from algebraic geometry: the derived pushforward and the derived pullback (of a flat morphism between suitable schemes). The strategy is WebSometimes we can compute the right derived functor of a composition. Suppose that be abelian categories. Let and be left exact functors. Assume that the right derived functors , , and are everywhere defined. Then there exists a canonical transformation of functors from to , see Lemma 13.14.16. This transformation need not always be an isomorphism.

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 ...
