Characteristic Classes,In this section we consider a fixed commutative ring k. Let us recall that the inclusion i: Z → X of a closed subspace gives rise to two functors . which are mutually adjoints . The functor i. is left exact and carries injectives into injectives. We shall study the derived functor R.i., p ∈?.

Application to Algebraic Geometry,In this chapter we shall give an introduction to the topology of algebraic varieties over the complex numbers. For all unexplained notation we refer to Fulton (1).

Derived Categories,Let us consider an additive category K and a system S of morphisms subjected to conditions FR 1, 2, 3 below. To these data we shall associate an additive category S.κ
