Intersection Products,in A.(.), . = .. (.). Although the case of primary interest is when . is a closed imbedding, so . = . ∩ ., there is significant benefit in allowing general morphisms .. Let .: . → . be the induced morphism. The normal cone ... to . in . is a closed subcone of .* ..., of pure dimension .. We define .

Excess and Residual Intersections,, .). If a closed subscheme . of . ∩ . is given, the basic problem of residual intersections is to write . · . as the sum of a class on . and a class on a “residual set” .. There is a canonical choice for the class on ., namely.where . is the restriction to . of ..., and .(., .) is the Segre class.

Positivity,rsection class has a corresponding decomposition into Σ .. α., α. ∈ ..(..), (..)=Supp(..). If the bundle . is suitably positive, one can deduce corresponding positivity of the intersection classes, even if the intersections are not proper.

Correspondences,re of the graph of a rational map, are basic examples, but more general correspondences have played an important role in the development of algebraic geometry. On complete non-singular varieties correspondences have a product β ∘ α, and a correspondence α: . ⊢ . determines homomorphisms α. from .(.)

Bivariant Intersection Theory,or all .′ → ., .′ = . ×..′, all .. In this chapter we formalize the study of such operations. For any morphism .: . → ., a . in . is a collection of homomorphisms from ...′ to ...′, for all .′ → ., all ., compatible with push-forward, pull-back, and intersection products.

Auf der Grundlage dieser Theorie ist es möglich, Transistoren mit spezifischen Eigenschaften zu entwickeln und die endgültigen Daten für gegebene Strukturen vorauszuberechnen. Diese Theorie stellt die Ausgangsbasis für den mit d
