Since 2012 I have been working as a graduate student at Harvard University, studying topics relating to the geometry and p-adic Hodge theory of Shimura varieties and related structures with a view to applications in the theory of Galois representations.

comment Serious introduction to the Langlands program for nonspecialist
Ed Frenkel's introduction to the Geometric Langlands programme includes a cursory overview of the "classical" Langlands programme which you might find useful. In terms of understanding anything properly, I think there is just too much out there to learn and you'll have to narrow down the question a bit first.

comment About the restriction of a modular representation to a decomposition subgroup II
No. I originally posted saying that I wasn't sure what is known about semisimplicity in general (I had a vague idea it was known in some cases and conjectured in the rest but not sure which). Thanks to "community" for clearing it up.

comment Bloch Kato Exponential as formal lie group exponential
I'd assume it's the inverse (which he mentions should exist on a small enough neighbourhood) to the logarithm in the sense of section 2 of Tate's article on p-divisible groups fhoermann.org/Tate%20-%20p-Divisible%20Groups.pdf

comment Is there a better proof of this fact in number theory/formal group theory?
<troll> In the divisibility poset $0$ is maximal, so surely it's appropriate to say it's the greatest common divisor of an empty set? </troll>

comment Automorphisms of profinite groups
Is this the $p$-part of the profinite completion of a free (nonabelian) group on $d$ generators?

comment “Why” is every polynomial representation of SL(2) selfdual?
Why is this? Do you need $p$ odd? (In the case $p=2$ it looks to me like perhaps conjugating by the matrix with 1s along the antidiagonal should exhibit self-duality, unless I've made a foolish error, which is likely).

comment What are limits of discrete series and which are cohomological?
Thank you, those references are extremely helpful.

comment Maximum dimension of an isotropic subspace in a quadratic space
Of course I meant $U$. So I was suggesting if you take the projection map $V \rightarrow U$, its kernel is negative definite, so in particular intersects any isotropic subspace trivially, so under this map, isotropic subspaces are embedded as subspaces of U.

comment Maximum dimension of an isotropic subspace in a quadratic space
You could consider the projection map onto the positive definite subspace?
