I am currently a Maître de Conférences in Saint-Étienne, in France. I am particularly interested in Number Theory and Arithmetic Geometry.

How frequently is 3 a cubic residue mod primes in an arithmetic progression?
Nice, but I do not understand why you chek that $2$, rather than $3$, be a cubic non-residue. |

Transcendental numbers in the p-adic rationals $\mathbb Q_p$
It seems to me that one way to turn the question into a meaningful one (although may be uninteresting to the OP) is to ask whether there exists an explicit way to tell whether an element of $\mathbb{C}_p$ (or of $\overline{\mathbb{Q}_p}$ or of any field $K\supseteq\mathbb{Q}_p$) which is trascendental over $\mathbb{Q}$ is already in $\mathbb{Q}_p$: like testing whether a trascendental complex number is real but in the $p$-adic world. If $K/\mathbb{Q}_p$ is not Galois, it seems interesting. |

Example of a non-smooth irreducible component of the generic fibre of a Hida family?
@KevinVentullo: Yes, thanks! I was able to download it and it contains pretty much what I was looking for. |

@Kevin(B.): sorry for my comment which is not related to your question, but do you have an explicit reference where computations/examples are made/provided for a CM family meeting a non-CM one? Thanks. |

Isomorphism related to the first cohomology group
Are you sure of this isomorphism? It sounds a bit strange in this generality: one a one hand, $\mathcal{O}_1^\times\times\mathcal{O}_2^\times$ is not isomorphic to the units of $L$ (to convince yourself, take $K_i$ to be totally real and compare $\mathbb{Z}$-ranks), and the inertia groups may very well not be cyclic...Do you have any reference where this is at least stated? |

What is “restriction of scalars” for a torus?
Great answer: one of the clearer and more concise description of Weil restriction I have ever found. |
