This paper just appeared on the arxiv this morning. It’s a play which tells about some of the history of Pfister forms. Apparently it was performed at Oberwolfach in 1992 in front of Albrecht Pfister himself. If you’re a fan of Hamlet and mathematics, then you definitely can’t pass this up. It’s probably the best math paper ever.
Update: I just spoke with Marc Masdeu about this paper, and he pointed out that Prof. Minac has written a bunch of mathematical plays. As of now only the Hamlet play is available for download, but you can read all of the hillarious titles here.
