PATRI

Deformation to the Normal Cone,together with the “principle of continuity” that intersection products should vary nicely in families, explains the prominent role to be played by the normal cone in constructing intersection products.

Excess and Residual Intersections,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. Our problem is therefore to compute this class on ., and to construct and compute a residual intersection class ? in ..(.), for an appropriate closed set . such that . ∪ . = . ∩ ., with..
