Essentially, they are a tool which allows you to systematically keep track of intersection cohomology. You can find a good picturesque introduction in MacPhersons "Intersection Homology and Perverse Sheaves".

WebMar 6, 2024 · Derived Pushforward on P1 One nice set of examples of constructible sheaves come from the derived pushforward (with or without compact support) of a local system on U = P 1 − { 0, 1, ∞ }. Since any loop around ∞ is homotopic to a loop around 0, 1 we only have to describe the monodromy around 0 and 1. WebThe derived category of constructible sheaves.

Webgenerator G of D(X) the Frobenius pushforward Fe ∗G generates the bounded derived category for whenever pe is larger than the codepth of X, an invariant that is a measure of the singularity of X. The conclusion holds for all positive integers e when X is locally complete intersection. The question of when one can take G = O X is also ...

WebPushforward of Coherent Sheaf Along Projective Morphism. 1. Sheaf associated to global sections of a quasicoherent sheaf is the pushforward by the structure morphism. 2. Stalk of pushforward sheaf on affine line. Hot Network Questions The Jaccard Index 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.
WebMar 31, 2024 · Solution 1. I think what you are saying is (almost) true: it works in the derived category. Below, for a scheme map α, we denote α ∗ to be the derived functor L α ∗ and denote α ∗ to be the derived functor R α ∗. Also, D q c ( −) denotes the derived category of sheaves of modules with quasi-coherent cohomology. chi memorial family practice soddy daisy tnWebFeb 29, 2016 · Specifically, we derived an expression for the pushforward of any vector (in coordinate basis), so the pushforward of just the basis vectors is a simple instance of the more general expression Suggested … chi memorial hackedWebThe intuition that left D-modules correspond to systems of linear PDEs will prove enlightening when we later construct the pullback and pushforward functors for D-modules. 3.
