函子的导出范畴与层的Fourier-Mukai变换

Derived categories of functors and Fourier--Mukai transform for quiver sheaves

Paula Olga Gneri, Marcos Jardim

摘要:

设C是小范畴,A是任意范畴.考虑范畴C(A),它的对象是从C到A的函子,它的态射是自然变换。给定一个函子F:A --> B,得到一个导出函子F_C:C(A)--> C(B)。若A和B是阿贝尔范畴,则C(A)和C(B)也是阿贝尔范畴,且有两个函子R(F_C):D(C(A))--> D(C(B))和(RF)_ C:C(D(A))--> C(D(B)).本文的目的是:1)找到D(C(A))与C(D(A))之间的关系; 2)把函子R(F_C)与(RF)_C联系起来。作为应用,我们证明了一个版本的Mukai定理的层。

英文摘要:

Let C be small category and A an arbitrary category. Consider the category C(A) whose objects are functors from C to A, and whose morphisms are natural transformations. Given a functor F : A --> B one obtains an induced functor F_C : C(A) --> C(B) . If A and B are abelian categories, we have that C(A) and C(B) are also abelian, and one has two functors R(F_C) : D(C(A)) --> D(C(B)) and (RF)_ C : C(D(A)) --> C(D (B)). The goals of this paper are: 1) to find a relationship between D (C(A)) and C(D(A)); 2) to relate the functors R(F_C) and (RF)_C. As an application, we prove a version of Mukai's Theorem for quiver sheaves.
