| May 30 at 7:19 | comment | added | Yulia Kuznetsova | What is C*(S,R) for a topological space S? Did you mean Cb(S,R) = the space of continuous bounded functions? Or, if S is locally compact, one can consider the space C0(S,R) of continuous functions vanishing at infinity. To speak of C*-algebras, you would need a semigroup structure on S. | |

| May 26 at 9:15 | comment | added | KP Hart | Just to be sure: "$A$ separates the points of $A$" should probably be "$A$ separates the points of $S$". And shouldn't $\gamma S$ be $\gamma A$?, the spectrum of the algebra $A$? | |
