ICM2014 — Bhargava, Gentry, Sanders

September 7, 2014

On my last day at the ICM I ended up going to fewer talks. As on the previous two days the first plenary lecture was not to be missed — it was Maryam Mirzakhani — so despite my mounting tiredness I set my alarm appropriately. I was a little surprised when I got there by just how empty it was, until eventually I saw that on the screens at the front it said that the lecture was cancelled because of her Fields medallist’s lecture the following Tuesday. I belonged to the small minority that had not noticed this, partly because I have had a lot of trouble with my supposedly-smart phone so was there with a temporary and very primitive replacement which was not the kind of phone on to which one could download a special ICM app that kept one up to date with things like this. I had planned to skip the second lecture of the morning, so I slightly rued my lost couple of hours of potential sleep, while also looking forward to being able to use those hours to work, or perhaps make progress with writing these posts — I can’t remember which of the two I ended up doing.

As a result, the first talk I went to was Manjul Bhargava’s plenary lecture, which was another superb example of what a plenary lecture should be like. Like Jim Arthur, he began by telling us an absolutely central general problem in number theory, but interestingly it wasn’t the same problem — though it is related.
