| Nov 24, 2010 at 17:54 | comment | added | Yemon Choi | I think you need to reword your question to be a little more precise. Presumably you are really interested in the case of $\sigma$-finite, properly infinite von Neumann algebras? eom.springer.de/v/v096900.htm | |
| Nov 24, 2010 at 17:52 | comment | added | Yemon Choi | in line with Dmitri's answer below: when you say that there is a unique tracial state, I think you mean to say that on a finite factor there is a unique faithful normal tracial state. Otherwise, consider $\ell^\infty$. | |
