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

comment Is every abelian group a colimit of copies of Z?
I have a stupid question: why can you assume $ne_i=e_j$ instead of $ne_i=me_j$? In this $p$-adic case they are probably equivalent since only the $p$-adic valuation matters but in general isn't it like assuming that $J$ be ordered or filtered?

comment Axiomatizing Gross-Zagier formulae
Beautiful answer! As for your final question about these points being related to Heegner points, do you ethink one expects Heegner points at all along some anticyclotomic extension of the field at hand?

comment When complex conjugation lies in the center of a Galois group
You're perfectly right, I had overlooked your assumption while answering. I erased the portion of text in question.

comment Where to buy premium white chalk in the U.S., like they have at RIMS?
The very sad news, which I got from a Japanese colleague yesterday, is that Rakuten is closing end of March because of some economical issue. So, hurry up!

comment Why no abelian varieties over Z?
@ Emerton: but oddly enough, Khare-Wintenberger need an inductive argument whose basic step relies upon Schoof's work on abelian varieties over number field with few bad places... ;)

comment Why is Class Field Theory the same as Langlands for GL_1?
@Kimball: I have downloaded the notes, but on page 115 you say that there is an isomorphisms between the idèle class group and the Galois group of $K^\text{ab}$, whereas I think you should mod-out by the connected component. This should create some discrepancy between "Galois characters" and "Hecke characters", no?

By definition, $U_E$ are the units, so all its elements are invertible...
