The American Institute of Mathematics has a great program for what they call focused collaborative research: SQuaREs, which stands for “Structured Quartet Research Ensembles”. A small group, between 4 and 6 members, applies with a particular research project. The groups that are supported spend a week at AIM working on the project, with the possibility of returning.
I am part of a 6 people SQuaRE group, working on “Descriptive aspects of Inner model theory”. The first meeting took place on May 16-20, 2011, you can see a picture here. This year we met for a follow-up, on April 16-20.
These meetings are fantastic, I think. Of course, they are exhausting and quite intense, but they pay off handsomely.
I expect I’ll be posting soon on some of our results.
