- First of all, let me to add to the bibliography the book
- we have just
- got:
-
- Sheaves in Geometry and Logic,
- By S MacLane and Ieke Moerdijk, Springer.
-
- Nice book.
-
- Second, I want to ask if some Topos/Sheaf fanatic have studied
- relationship between the generalized spaces etc of Topos theory,
- and the non-conmutative "spaces" of Alain Connes.
- Im not expert in the matter, so I could be asking a nonsense.
- Anyway, a motivation for the question is that the Kroneker
- foliation of the bidimensional torus, which were the main example
- of Connes' theory, is also one principal example of Sheaf/Topos
- theory when used to calculate De Rham Homology. At least, it is
- used by Moerdijk (althought not in that book) to show all the
- constructios of clasifiyng topos, BG etc...
