Trigonometric polynomials on non-compact and non-abelian groups
Yemon, could you, please, make a little paper from this (for example, in arxiv), so that I could cite it? A separate request: if ${\tt Trig}(G)$ is not an algebra even for Moore groups, then this should be mentioned there, because this is an important proposition for me. |

What are the reasons for considering rings without identity?
Yemon, I don't understand you. Does anybody consider $\ell^1({\mathbb T})$? The stereotype theory suggests several natural group algebras, in particular, the algebra of measures ${\mathcal C}^\star(G)$, the algebra of distributions ${\mathcal E}^\star(G)$, etc., and they are all Hopf algebras in contrast to $L^1(G)$. The full measure algebra $M({\mathbb T})$ is unital, but it is not a Hopf algebra and not a group algebra, since it does not generate equivalence between representations (of $\mathbb T$ and of $M({\mathbb T})$). |

OK. They will be my heroes as well. :) |

Александр Игоревич, хочу с вами подружиться. :) If you don't mind, I'll continue this discussion by e-mail. :) |

Is this true for Moore groups (where every irreducible unitary representation is finite dimensional)? |

Are there at least some natural classes of groups, where this is true? |

Are norm-continuous representations smooth?
It's strange, that there is no direct reference. |

Is it possible that $H_\infty=H$ when $\rho$ is norm-continuous? |
