Parts and Whole / 1 September 2013
TANAKA Akio
I was ever simply thinking that the parts gathers and the whole is completed. But the situation seemed not to be so simple, I recently realised. Its beginning started with 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).
