Lci morphism
WebFor an lci morphism f: X!Y, factor it as above, f= p i. Then de ne f! = i! M Y p!. Proposition 3.1 Let f: X!Ybe an equivariant locally complete intersection morphism of quasi-projective G-varieties. Then 1. f! 2KK G(X;Y) is independent of all choices in its construction. In particular, the two constructions de ne the same class in KK G(X;Y). 2 ...

WebDe nition 2.2. We say that a morphism of schemes is lci (\locally complete intersection") if it is of nite type and it factors locally as a (closed) regular embedding followed by a smooth … Webmorphism. I don’tknow whyone wouldn’t more generallythink of factorizations into alocal com-plete intersection followed by a flat morphism. I gave you a few examples as to why you might care about such morphisms. Here is another. If X and Y are smooth then any morphism between them is an lci morphism. Reason: factor it into X ,→ X× Y → Y.
