@Zhen Lin, thank you for the comment, but if you could provide me some reference to these in order that I can get more precise ideas about these in the future.

@Zhen Lin, I don't understand what this menas "lifting constructions on Set to constructions on Sh(X)". Also could you explain or give a reference that illustrate what is the relation between this with local ring, thank you.

comment complex multiplication
@kreck, I felt strange that it is written that "...be a quaternion algebra over a quadratic field...". It is good to know that it contains an imaginary quadratic field and the theorem Tate proved. Could you give the reference for it. Thank you very much.
