## Short Items

The Fermilab Physics Advisory Committee recently recommended that the Tevatron be kept running for an additional three years (until 2014). By the end of that time it should be able to accumulate a total of 20 fb-1 of data, which … Continue reading

## Langlands/Frenkel and Some Other Things

The Canadian publication The Walrus today has a wonderful article about Robert Langlands, focusing on his attitude towards the geometric Langlands program and its talented proponent Edward Frenkel. I watched Frenkel’s talk at the ongoing Minnesota conference via streaming video … 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

## 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

## 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
