## MA598R: Measure Theory

In the summer of 2007, I had the pleasure to help a group of graduate students prepare for their Qualifying exams in Measure Theory.   I taught the course MA598R, which was mainly a thorough review of Torchinsky’s “Real Variables”, together with guided sessions of problem-solving from previous Qualifying exams and lists of problems from Rudin, Torchinsky, Lieb-Loss, and other sources.

## Lesson Plan and Assignments

Feel free to download the different problem sets below.  In a near future I will also present hints and solutions to some of the harder exercises.

Hi Francisco,

I’m a new graduate student in Purdue. I found some links in Prof. Bell’s homepage, including the nice problems you created in the 2007 summer to help students prepare quals. I spent a lot of time thinkng about the ” advanced problems 18″ but still don’t know where to start. I’m sorry to ask you about this now. It has been 7 years’ long since you gave the problems, but I’ve been tortured by it for a long long time.
I couldn’t get asleep these days because of this problem. I tood a glance of all the books you listed but didn’t find any hint. I think the key to the problem should be the Plancherel Theorem, but I don’t know where to start. Could you please give me some clues whenever you are free?

Best,
Qinfeng

Qinfeng, thanks for reading! I posted a solution to this problem at the following [link]. Let me know if that helps.
