| Oct 8, 2023 at 11:23 | comment | added | Ali Taghavi | @DavidRoberts I am reading your post below to have a better imagination of the story: I think you are indicating to woronowich morphism. any way what would be happen if I simply assume that the morphisms are usual morphisms between C^* algebras(According to my main question in this post)? | |
| Oct 8, 2023 at 11:13 | comment | added | David Roberts♦ | @Ali I assume you mean strictly continuous, though? I was just curious, that's all. | |
| Oct 8, 2023 at 8:35 | comment | added | Ali Taghavi | @DavidRoberts Yes w consider all possible morphisms(unital or non unital). However the "exclusively unital morphisms" produce another question | |
| Oct 2, 2023 at 21:42 | comment | added | David Roberts♦ | @Ali I mean to ask what are the morphisms? And do you mean to include non unital ones? | |

| May 24, 2023 at 6:29 | comment | added | Ali Taghavi | A space X is approximately sigma compact if it has a dense sigma compact subspace. For exqmple the long line is not approximately sigma compqct | |
| May 24, 2023 at 6:27 | comment | added | Ali Taghavi | @YemonChoi Yes algebras you mentioned are not $Z^*$ algebra. But a commutative algebra $C_0(X)$ is a $Z^*$ algebra iff $X$ is not approximately sigma compact | |

| May 24, 2023 at 3:11 | comment | added | Yemon Choi | Where does this definition come from? Note that $C(X)$ is not a $Z^*$-algebra for any compact X, and also $C_0({\mathbb R}^n)$ is not a $Z^*$-algebra. Unital $C^*$-algebras are not $Z^*$-algebras. | |
