Parts and Whole / 1 September 2013

I was evwe simply thinking that parts gather and the whole is completed. But the situation seemed not to be so simple, I realised  recently. Its begining starts from a theorem of arithmetic geometry.

 

Theorem
When i : X–>Y,  j : Y–>Z is regular closed immersion of their codimension c, d, the next is set up.
(jOi)* = j*Oi*: CHr(Z) –>CHr-c-d(X).
