| Sep 22, 2011 at 22:01 | comment | added | Benjamin Steinberg | That is finite groups. | |
| Sep 22, 2011 at 22:01 | comment | added | Benjamin Steinberg | The paper projecteuclid.org/… of Rieffel characterizes group algebras of groups over the reals as ordered algebras (ordering functions on the group pointwise). | |
| Sep 22, 2011 at 20:48 | comment | added | lwassink | I mean $C_c(G)$ - continuous compactly supported functions. Thanks for the clarification. | |
| Sep 22, 2011 at 20:42 | comment | added | Yemon Choi | When you say group algebra, are you completing this in some norm? (Otherwise your mention of "locally compact groups" sounds strange.) If so, do you mean $L^1(G)$, or $C_r^*(G)$, or $C^*(G)$, or something else? | |
