WebTHE GEISSER-LEVINE METHOD REVISITED 5 the derived category by L(n)X.For X smooth, we denote similarly by Z(n)X the complex of Zariski sheaves associated to U 7!Z(U;n), and by Z(n)X its class in the derived category. Theorem 1.2 f) implies that, for X quasi-projective, there are isomorphisms for all n;q Webderived categories and derived functors between them, provides a significantly richer and more flexible machinery than the “old” homological algebra. For instance, the important concepts of dualizing complex and tilting complex do not exist in the “old” homological algebra. 1. The homotopy category 431 2. The derived category 434 3.
