WebIntroduction the Derived Categories The spectral sequence of a composite functor is a powerful tool, but it nonetheless does not provide a way of calculating the derived … Webderived category of coherent sheaves of a scheme, particularly focus-ing on the notion of the Fourier-Mukai transform and mention a few results of importance. In Section 3 we give a quick overview of K-theory2, Chow groups, the Chern character and the Riemann-Roch Theorem. In Section 4, we say a bit about the conjectural notion of
WebLet us recall the definition of a full exceptional collection in a k-linear triangulated category T. Definition 1. An object Ein T is said to be exceptional if Ext•(E,E)=k. Definition 2. A sequence of objects E 1,...,E m in T is called an exceptional collection if all E i are exceptional and Ext•(E i,E j)=0for all i>j. A collection (E 1 ...
