Algebraic and enumerative combinatorics seminar
We view algebraic combinatorics broadly, explictly including algebraic enumeration and related asymptotic and bijective combinatorics as well as algebraic combinatorics as it appears in pure algebra and in applications outside mathematics.
We are trying having a pre-seminar which is designed to get participants up to speed on useful and interesting background for the talk. It will be at the level for beginning grad students. Then there will be a short coffee break followed by the seminar itself.
Our audience consists principally of combinatorics faculty and grad students. Seminar talks are 50 minutes with questions following.
If you are speaking, we need your abstract at least a week in advance so it can make the deadline for the Friday math faculty seminar mailing.
