Questions about Witten's recent articles

[ehrenfest]

Hello,

Someone at my school whom I want to impress is going to speak about Witten's recent articles about CFT: http://www.slac.stanford.edu/spires/find/hep/www?rawcmd=ea+Witten,+Edward
Can someone give me some intelligent-sounding questions about these articles?

I don't think you will impress him in that way.
BTW, you gave a link to the list of ALL Witten's papers. The fact that you were not able to pick specific papers does not impress either.
