Today we'll look at these problems concerning games and processes: game-prac-nosol.pdf -- without solutions, emailed before meeting game-prac.pdf -- with solutions, not readable until meeting As usual the first page has some problems, the second page has hints, and the remaining page(s) have solutions. The solutions today are all from Kedlaya's Putnam archive. My apologies to Srijon and Enoc, who saw some of these last year. We only have 6 remaining Fridays: 10/25, 11/1, 11/8, 11/15, 1/22, 12/6. I omit 11/29 for Thanksgiving. The Putnam itself is Saturday 12/7. Any suggestions for future meetings? (combinatorics, algebra, etc.)
