I visited the University of Pennsylvania on Tuesday, and while I was there, Ron Donagi told me about an upcoming conference at UPenn, called “String-Math 2011”. It’s a week-long meeting, June 6-11, with a bunch of exciting people on the visitor list. And it’s the first of a series of such conferences. If you want to know more, the conference webpage is

The early registration deadline is April 2nd.

In other news, like my co-bloggers, I’m teaching a class this semester: Quantum Field Theory for Mathematicians, which aims to explain the basic ideas of quantum field theory through the study of mathematically well-defined examples. In particular, we’re looking to see how Wilson’s “effective field theory” philosophy motivates the rigorous constructions of the path integral measures. I’ve been putting my lecture notes online; you’re welcome to check them out if you’re interested. (There have only been 3 lectures so far; we’re still on preliminary material. However, you can see from the syllabus what I’m hoping to cover.)

Somewhat off topic: How did you scan your notes so that the black stays genuine black while the other colors are preserved? Or did you write your notes on a pen tablet? If so, what application did you use to do that?

I used Xournal, which is pretty much the default pen tablet application on Linux.

Thanks!

Nice notes. I have added a link to the nLab’s page on path integrals.

http://ncatlab.org/nlab/show/path+integral

(Though currently that page is still a stub and a mess. But some day, hopefully, somebody will take care of it and make it a good resource for moden mathematical treatments of path integral and QFT via path integrals.)
