Kapranov's analogies

There are notes from more recent (2000) lectures of Kapranov on the subject on my webpage. Despite this, as far as I know, there isn't any convincing argument at this point that there should be a gen …

What are the local Langlands conjectures nowadays, for connected reductive groups over a $p$...

To elaborate on Marty's comment, the simple moral one learns from both the Kazhdan-Lusztig classification of tamely ramified representations and the real local Langlands classification is that L-packe …

What is a tamely-ramified Weil-Deligne representation?

This is more of an extended comment. If I'm understanding the question correctly, I don't believe it's correct to say that tamely ramified Galois representations with unipotent monodromy correspond pr …

What are the local Langlands conjectures nowadays, for connected reductive groups over a $p$...

A brief update: in his amazing talk yesterday at MSRI (available here), Laurent Fargues explained (building on work of Peter Scholze, see his phenomenal talk two weeks ago here and his historic Berkel …

Why is Langlands functoriality usually related with period integral in a third group?

I'm not close to familiar enough with the references you cite or examples you ask about to address them, but here's a picture coming out of Sakellaridis and Venkatesh [SV]. Let us label a period not b …

New Geometric Methods in Number Theory and Automorphic Forms

To complement Joel's wonderful and (as far as I understand) very much on point answer, let me quote from the proposal for the parallel program on Geometric Representation Theory, which touches on seve …

Categorical-geometric Langlands for tori

In case $G=T$ is a torus and $G^\vee=T^\vee$ is the dual torus, the geometric Langlands conjecture — or “categorical geometric class field theory” (for a smooth projective curve $C$ over $\mathbb C$) …

Relationship between the TQFTs in Kapustin-Witten and Ben-Zvi-Sakellaridis-Venkatesh

The (fairly poetic and ill-formed) idea in this story is that the Kapustin-Witten story and the Langlands program are about the SAME four-dimensional TQFTs, but evaluated on different "manifolds" - i. …

How can I see the relation between shtukas and the Langlands conjecture?

I was hoping someone arithmetically qualified would take this on, but here are some comments from a geometer. One nice perspective I learned from Wei Zhang's ICM address - namely, over function fields …

Implications and consequences of the recent proof of the geometric Langlands conjecture

To avoid writing a long essay I'll be very telegraphic. Here are some of the many open problems that are reasonably "next" in the area. I'll use [GLC] to refer to the recent papers proving the unramif …
