Geometric Langlands at the KITP

There’s a very interesting program going on at the KITP discussing recent work of mathematical interest on 4d supersymmetric gauge theories (N=2 and N=4). These include various connections of 4d gauge theory to geometric Langlands uncovered by Witten and collaborators … Continue reading

Latest Langlands

The site at UBC collecting the work of Robert Langlands is now no longer being maintained. There’s a new site now at the IAS. It includes some interesting recent short articles of various kinds that I hadn’t seen before, including … Continue reading

Gauge Theory and Langlands Duality

At the KITP in Santa Barbara there’s a wonderful program on Gauge Theory and Langlands Duality starting up this week, with some of the talks beginning to become available. The main topic will be the relations between S-duality in quantum … Continue reading

Geometric Langlands and QFT

Wednesday’s session at the IAS Conference on Gauge Theory and Representation Theory was mostly devoted to talks by Witten and his collaborators about their latest work on the approach to relating geometric Langlands and QFT that he has pioneered over … Continue reading

Langlands on Langlands

In a forthcoming issue of the AMS Bulletin, there will be a long review by Robert Langlands of the book p-adic Automorphic Forms on Shimura Varieties by Haruzo Hida. The book itself is on a very technical subject, but the … Continue reading

More On Geometric Langlands (a Grand Unified Theory of Math?)

After mentioning in the last posting that Witten is giving talks in Berkeley and Cambridge this week, I found out about various recent developments in Geometric Langlands, some of which Witten presumably will be talking about. Edward Frenkel has put … Continue reading

Witten Geometric Langlands Talk and Paper

I spent yesterday afternoon down in Princeton, and attended a talk by Witten at the Institute on his work relating gauge theory and the geometric Langlands program. He says that his paper with Kapustin is done, it’s about 220 pages … Continue reading

Geometric Langlands on the Beach

I’ve written a bit about the Geometric Langlands Program and its relation to physics here late last year, confessing to being confused about what it was supposed to have to do with N=4 supersymmetric Yang-Mills. Yesterday Witten gave a talk … Continue reading

Langlands Program and Physics

One of my minor hobbies over the years has been trying to understand something about the Langlands conjectures in number theory, partly because some of the mathematics that shows up there looks like it might be somehow related to quantum … Continue reading
