comment local galois representation with higher coefficient
You also changed the setting completely. Is $F$ an extension of $K$ or a subfield of $K$??

comment Is there a “trianguline period ring”, or is one expected?
This ring has not been studied. At some point, my student Di Matteo was interested in it, so you could ask him.

comment Valuations on tensor products
Isn't this just a matter of saying $v(b \otimes c) = v(b) + v(c)$ and letting the valuation of an element of $B \otimes C$ be the sup, over all possible ways to write the element as $\sum b_i \otimes c_i$, of $\inf_i v(b_i \otimes c_i)$?

comment (phi, Gamma) module of ordinary elliptic curve
The references above will (I think) give you the corresponding filtered $\phi$-module, but not the $(\phi,\Gamma)$-module.

comment Incidences of rigorous proofs used in legal proceedings
Our students (at the ENS de Lyon) like AC very much when they hear about it, to the point that they feel that they need it in order to choose one element from a set of two.

comment Where to find Asterisque online?
@quid: yes you're right. In my defense, the "Astérisque" style of 10 years ago looks very much like the "brochure" style of today.

comment Where to find Asterisque online?
The Bourbaki seminars that are available on Numdam are the versions that the authors hand out before their talk. They're not the final versions that are published in Asterisque.

comment What are p-adic period rings?
These are very good examples! Another example is that these rings of periods can be used to define the $H^1_f$ groups "at p".
