The last 3 posts were chapters from my PhD qualifying exam at UCSD, which I wrote over the course of 12 days (to the hour!) from Dec 12th to Dec 24th, 2013. It's a document I had to write so that I could start working on my dissertation. The stuff I wrote may make it into a publication or two, but in the meantime I thought it'd be nice to share it on the internet. In case my server doesn't display the equations right, you can grab the print version here. I recommend reading it in bed, as a cure for insomnia. 😉 Enjoy!
