| Jun 13, 2011 at 6:21 | comment | added | Yemon Choi | I think you are being a bit hasty: you need not just a smooth subalgebra but a spectral triple, as the other answers and comments have pointed out. Since A is a smooth subalgebra of A, I think more is needed in order to encode some notion of NC manifold... (If you want slightly less fatuous examples, then take something like $\ell^1({\mathbb Z})$ viewed as a dense *-subalgebra of $C^*({\mathbb Z})\cong C({\mathbb T})$.) | |
