| May 3, 2016 at 2:16 | comment | added | epsilon | I guess the answer to my question is: It's not known. It's an open problem. | |

| Apr 28, 2016 at 22:30 | comment | added | epsilon | I'm talking about an abstract dual operator algebra $A$ (that is, there is a Hilbert space H and a w$^{*}$-continuous completely isometric isomorphism $\pi:A\to B(H)$ ). I want to know if anybody has proven that there is a minimal $W^{*}$-algebra generated by $A$ (yes, considering all representations, just like in the case of the $C^{*}$-envelope of an operator algebra). | |

| Apr 28, 2016 at 7:04 | comment | added | Uri Bader | Are you conidering $A$ here a sub-algebra of operators of a given Hilbert space, or do you have in mind an "abstract" Banach algebra and you wish to define a ctegorical envelope considering all possible representations? | |
