What this is? Why am I doing it?
As is usual for a grad student, I read a bunch of articles, books etc. I've found that my understanding is greatly enhanced in the process of writing down an exposition/summary. I've thus decided to write-up these for important papers irrespective of whether I give a talk on these. I also hope that this would improve my writing skills which are terrible at best. If you ever do read any of these, I would love to hear about any errors/comments/suggestions you may have.
