Applications of $p$-adic Hodge theory
It plays a key role in proving modularity lifting theorems by making possible the study of local deformation rings for an l-adic representation at p=l. One can look at the section on Fontaine-Laffaille modules in Darmon-Diamond-Taylor for the start of this story I guess. |

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. |

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. |

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 |

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> |

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

“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). |

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