| Dec 1, 2014 at 11:23 | comment | added | Ali Taghavi | @AndréHenriques could you please more explain that why an interval with double ends is a counter example?May you explain in detail. Regarding your last statement I do not remember this example as an answer to my question. My only characterization of commutative algebra is the following. | |
| Nov 30, 2014 at 22:09 | comment | added | André Henriques | Here's the simplest example of a $C^*$-algebra that isn't Morita equivalent to a commutative $C^*$-algebra: functions from $[0,1]$ to 2x2-matrices, that take diagonal values at $0$. I think that it already provides a counterexample to your "characterization of commutative algebras". | |
| Nov 30, 2014 at 20:24 | comment | added | Ali Taghavi | @YemonChoi this would be a possible characterization of commutative algebra in term of $K$-theory, up to Morita equivalent. | |
| Nov 30, 2014 at 20:22 | comment | added | Yemon Choi | Why would it be interesting if such an object existed? and why would it be interesting if no such objects existed? | |
| Nov 30, 2014 at 20:19 | comment | added | Ali Taghavi | @AndréHenriques thank you for the comment. I revise my question. | |
