Cvitanovic's book, and apparently Cvitanovic himself (I've traded an email or two, but he's friends of friends -and seems to always make a big impression in person) is amazing. It's been around in some form or other since I was wrapping up my ph.d. thesis in a related subject, and I remember being mad as hell it didn't exist when I started as it had the most understandable explanations of the Gutzwiller trace formula. The late Dieter Wintgen's papers were also good, but not as didactic, and without so many examples. I should work out all the problem sets in J and publish the results. Seems like a properly impish trolling.
