comment Why does John the Baptist deny being "Elijah"?
Here's an interesting paper by a leading expert on the gospels that touches a lot on this topic a lot.

comment Is it possible to have a PhD advisor from another university?
I know a few examples of this happening in math, though it may be even rarer in other fields.

You need to talk to a lawyer in France and maybe to the US school about whether a January start is possible, there's no point talking to random academics on the Internet about this further until you understand your options better.

comment When is Rep(U_q(g)) invariant under q -> -q and why?
With the "usual" conventions the dimension of the 2d rep of $U_q(\mathfrak{sl}_2)$ is $q+q^{−1}$. Your formula has two changes. There's a variable $s$ with $s^L=q$ where $L$ is the index of the root lattice in the weight lattice (so $L=2$ for $\mathfrak{sl}_2$). You need this $s$ to write down the braiding. Your q is s, which explains the appearance of $q^2$ in your formula. The minus sign is coming because TL is not the "usual" pivotal structure (since it's real instead of quaternionic). (The latter point is not important since changing piv. str. won't affect whether Rep is symmetric.)

comment What advice would you give students applying for graduate school in mathematics?
@TobiasKildetoft I think it's pretty common for people to apply to a lot of postdocs. I "only" applied to around 25 myself, but I think that's definitely on the small end.

@Faheem The job market is tight accross all of academia. My impression is that most academic fields have even worse job markets than math. (Certainly the humanities, but also theoretical physics for example.)

Thanks! You're right, I miscopied from consecutive sentences.
