| Jan 28, 2011 at 1:34 | comment | added | XXX | Of course Γ and G should be Abelian. | |
| Jan 27, 2011 at 18:17 | comment | added | Bill Johnson | @Yemon (or whomever), do you remember why the characters cannot be ordered to be a Schauder basis for $L^1(G)$ for any compact Abelian metrizable group $G$? No credit for pointing to McGehee, Pigno, Smith, which anyway would cover just the case of the torus. I think Wojtaszczyk proved something more general (that a basis for $L_1$ that is bounded away from zero cannot be uniformly integrable, or something close to this), but ruling out the characters is easier, IIRC. | |
| Jan 27, 2011 at 17:17 | comment | added | Yemon Choi | XXX if that is what you want to ask, then that is what you should have asked. Also "what can we say about X" is in my view not a very well-posed question, in this or any other academic discipline. | |
| Jan 27, 2011 at 15:56 | comment | added | Bill Johnson | What do you mean by the dual of a compact non Abelian group? | |
| Jan 27, 2011 at 13:48 | comment | added | XXX | Suppose Γ is a comapct Lie Group， G is its dual， then I want to ask what can we say about G? | |
