This seminar gives graduate students the opportunity to hear and present talks on discrete mathematics, either on topics beyond a standard combinatorics class or on original research. GCS is meant to be a friendly, slightly informal speaking environment where questions are encouraged at all points throughout the talk. We only assume a basic general knowledge of combinatorics (at most, basic combinatorics one might learn in a single semester introductory course), so students in any area are welcome to attend.The 2021-2022 GCS webpage is here. The archive of talks until Spring 2020 is here. Back to Corrine's home page.
