What are Reinert's reproaches to the Ricardo theory?
And which reading do you recommend? |

Who is the author? Ethier? |

Does this mean that the theory that I am looking for (without those paradoxes) exists? |

Uniform definition of $S(\mathbb{R})$ and $S(\mathbb{Q}_p)$
For any LCA-group $G$ the multiplication by a real character on $\widehat{G}$ corresponds to the differentiation over a one-parametric subgroup in $G$, that's why I am speaking about polynomials. I don't know whether the multiplication by $|x|^k$ gives the same class of functions, I don't have intuition in $p$-adic fields. |

Yes, this seems to be true, if we change a bit the definition of a polynomial: $p$ must be locally representable as a finite linear combination of finite products of real characters. |

Uniform definition of $S(\mathbb{R})$ and $S(\mathbb{Q}_p)$
Your question is very vague... I can formulate a hypothesis: perhaps ${\mathcal S}(G)$ is the subspace in $L_2(G)$ consisting of functions $f:G\to{\mathbb C}$ such that $f$ and its Fourier transform $\hat{f}$ rest in $L_2$ after being multiplied by any polynomial $p$ (where a polynomial on $G$ is a linear combination of finite poducts of real characters, i.e. continuous homomorphisms $r:G\to{\mathbb R}$). I don't know, whether this is more intuitively reasonable (and whether this is true). |

Image of a Jordan compact set under a degenerate map
Igor, as far as I understand, Hajlasz proves that the $m$-th Hausdorff measure of $\varphi(K)$ vanishes, but why does this mean, that $T$ exists? |

I would not recognize. And I am afraid, I need somebody to explain this. Is there a simple way to prove this proposition, without entering this deep theory? |
