Northeast Combinatorics Network

Combinatorics is a rich and active area of mathematics. Throughout New England and New York, there are research groups involving faculty, postdocs, graduate students and undergraduates exploring intriguing problems and important questions in a wide range of topics within discrete mathematics. This website, like the meetings listed here, is intended to bring this community together to advance these important research programs.

                    Previous Conferences                             Virtual Combinatorics Colloquia (paused) 

Spring 2023 Discrete Math Workshop,  Smith College, Northampton, MA, Saturday May 6, 2023

The goal of this small, informal conference is to bring together regional combinatorialists for a day of 

collaboration, congeniality and an opportunity to learn about one another's investigations.

The meeting will begin at 10:00am and run until late afternoon.

Please register here before Sunday, April 30

If you are interested in giving a talk, please submit your title as soon as possible, and definitely by April 26.
