Fall 2012 seminar on complex analysis and combinatorics

Nicolas and Sam are running a learning seminar on many complex variables with applications to asymptotic combinatorics. This learning seminar can be taken as a reading course; please contact me if you are interested.

We will be in K9509, 11:30-1:30 Mondays. See below for the schedule. Dates are subject to change, especially later in the semester.

Older seminars on more motivic topics from when I was at Boston University. There are many broken links, but I consider these archived and so they will not be changed.
