Papers for the end of the semester talks

November 14, 2012

Below are papers for the end of the semester talks. It offers both classical as well as cutting edge results. The list will grow with time. I suggest you’ll read the abstracts, choose a paper and let me know if you want it so I will reserve it for you. Recall that the talks are in individuals, are on the board (not presentations) and should take 50-90 minutes. Most importantly – they should be great!
