| Dec 30, 2017 at 17:24 | comment | added | Simon Henry | Any such class is a dixmier douady class of a bundle of simple $C^*$-algebra. So you can find a bundle of algebra such that this holds. Moreover the construction of such a bundle is quitte explicite when your class is described in $H^2(M,U)$ where U is the sheaf of continuous complex function of module 1, which is your case here. | |
