Thank you, Yemon! |

Tangent space of the Fourier algebra $A(G)$
I thought, when $G$ is not discrete there must be at least usual derivatives $\frac{\partial}{\partial x_i}$... They are not continuous here? |

Tangent space of the Fourier algebra $A(G)$
Yemon, how can this be? There are non-smooth functions in $A(G)$? |

A generalization of real characters on a group
Neil, but I suppose you mean $A[t]/\{t^{n+1}\}$, the quotient algebra. |

@NeilStrickland, yes, excuse me for the mistake in the second condition! I corrected this. |

@YCor, yes initially $G$ and $A$ both were algebras. I reformulated this for the case when $G$ is a group. |

Yemon, I think you meant $A(G)\subseteq C_0(G)$. |

Ah, I see! No, I meant the usual set of zeroes: $\text{Ker}f=\{x:\ f(x)=0\}$. Yemon, where is this written, about "iff $G$ is amenable"? |

Yemon, thank you, yes, I mean the usual kernel. Actually, I don't know, in which other sense it can be understood. Can you give a reference? |

When is the induced representation factored through the initial one?
My $H$ is normal. Ben, I need a reference. I must refer to a textbook or to a paper in my text. |
