comment Are D_dR and D_st “potentially comparable”?
By the way, these "thin subsets" are called "parties fines" in our article. I suspect that my coauthor was playing a joke on me (and the readers) since I later found out that in French, "partie fine" also means "orgy".

comment local galois representation with higher coefficient
If you're looking at linear representations of $G$ with coefficients, then everything works "the same". See for example 3.1 of Breuil-Mézard's 2002 Duke paper.

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.
