I'm a PostDoc at the École normale supérieure de Lyon. I am interested in arithmetic geometry, especially the theory of p-adic modular forms.

Slope of classical modular forms @Joël: can you precise which Buzzard's paper are you talking about? Looking at the titles of his papers the word "Artin" appears just in one paper... |

Weil restriction of abelian schemes along finite étale (resp. finite locally free) morphisms Doesn't this work only for projective abelian schemes? |

Is there non-simple-connected projective variety(over C) with trivial etale fundamental group? Yes, you're right. I've added a reference. |

Is there non-simple-connected projective variety(over C) with trivial etale fundamental group? Yes, of course, the manifold must be algebraic! |

Is there non-simple-connected projective variety(over C) with trivial etale fundamental group? I don't understand your comment. The (topological) fundamental group depends only on the structure of topological space. A complex manifold is of course a topological space (with extra structure), so it has a topological fundamental group. |

Constructible topology on schemes @pz Can you explain where spectral spaces are used in the theory of Adic spaces? I mean, I know that Huber proved that adic spaces are spectral (maybe with some conditions), but I always thought that he did this just to give an idea of how to visualize the topology on the adic spaces (in contrast with Berkovich spaces that have a "real" topology) and not to prove anything about adic spaces. |

Is pi = log_a(b) for some integers a, b > 1? Is there a particular reason to consider $\pi$ and not other transcendental numbers? For example, is the problem known for $e$ or $\sum_i 10^{-i!}$? Just for curiosity, can you give an example of a number $x$ such that $a^x=b$ but $x$ is not defined as $\log_a(b)$ (I know this not a precise question)? |

New grand projects in contemporary math Dear Joël, thank you for the comment. I would like to stress once again that my sentence was just a personal opinion (based on my, very limited, knowledge on the subject) and was not intended to be taken very seriously. In any case I am very happy to know about the results you cited! |

New grand projects in contemporary math I really meant no. This is of course just a personal opinion (and am not an expert!). But I think there very important recent results in the local case, for example the local-global compatibility proved by Emerton. |

Which local ringed spaces are schemes? It gives a little more, you do not have to guess the isomorphism, just check that morphism. |
