About

The Atlantic Combinatorics seminar is a virtual seminar series aimed at the Combinatorics research community in Atlantic Canada. The seminars cover a broad range of topics in Combinatorics and Discrete Mathematics, with special attention on research topics represented among the Atlantic community, such as  games on graphs, graph polynomials, combinatorial game theory, and design theory. We encourage speakers to give an expository talk that is accessible to graduate and advanced undergraduate students. The seminar is held during the academic year on Wednesdays, 3.35-4.30pm Atlantic time, via zoom. Please  contact the organizer, Jeannette Janssen (jeannette.janssen@dal.ca) if you wish to receive the announcement and zoom link of the seminars.
