| Mar 30, 2016 at 7:15 | comment | added | hänsel | @Caleb: thanks, interesting. I am suspicious that the general case might not hold because perhaps you Need 2 out of 3 property, and $C^*(G)/J$ might for example not be amenable. | |

| Mar 20, 2016 at 22:23 | comment | added | hänsel | This might be a difficult question because even taking $J$ to be trivial the question is whether the rather arbitrary amenable $C^*$-Algebra $C^*(G)$ satisfies UCT. But it is unsettled if every amenable (separable) $C^*$-Algebra is in the boot strap class. | |
