Ramsey Theory Outreach

In the words of Imre Leader, a Professor at the Cambridge University: "The fundamental kind of question Ramsey theory asks is: can one always find order in chaos? If so, how much? Just how large a slice of chaos do we need to be sure to find a particular amount of order in it?"

Frank Plumpton Ramsey (1903–1930) was a British mathematician, philosopher, and economist who made major contributions to all three fields.

The theorem that Ramsey established in 1930, now known as Ramsey's theorem, turned out to be a source of inspiration for generations of mathematicians.

This Ramsey Theory Outreach page is a collection of resources that may help the reader with their search for an approachable introduction to Ramsey theory. It is the hope that these resources will be valuable for anyone interested in becoming familiar with this dynamic segment of contemporary mathematics that combines, among others, ideas from number theory and combinatorics.

Currently the page includes:

Ramsey Theory Podcast: No Strangers At This Party

The "Ramsey Theory Podcast: No Strangers At This Party" was created by a group of students from Simon Fraser University in Fall 2021: Knute Hardin, Harleen Kaur, Wassim Khelifi, Brian Krammer, Connor Marriam, Stephen Ng, Payal Payal, Amritha Raj Kizhakkeputhukulathil Ramanan, Anmol Anmol Singh, and Manan Sood.

This podcast celebrates Ramsey theory and the people working in this dynamic field of modern mathematics.

Through their conversations with undergraduate students, some of today's most notable Ramsey theorists talk about their first experiences with mathematics, their times as undergraduate and graduate students, their views about Ramsey theory and mathematics in general, and about their research interests. 

The podcasts are available on the following podcast services: SpotifyAnchorApple Podcasts, and Google Podcasts.

The episodes were edited by Aidan Wright. The background music was composed and performed by Nina Djokić. Both Aidan and Nina were students in the Fall 2020 “Introduction to Ramsey Theory” class taught by Veselin Jungić.

All podcast covers were created by Manan Sood.

All photos were courtesy of the interviewees. The photo of Dr. Joel Spencer is by Mary Ann Spencer. The drawing of Frank Ramsey was created by Veselin Jungić and Simon Roy.

The producer of the series was Veselin Jungić.

"Introduction To Ramsey Theory" - Students' Projects

This collection contains 25 group projects completed by students enrolled in three different "Introduction To Ramsey Theory" courses offered by the Department of Mathematics, Simon Fraser University. 

The purpose of the projects was to give each student an opportunity to understand a segment of Ramsey theory in a deeper way by working on a Ramsey theory related theme in a group setting.

The diversity of the presented projects reflects the diversity of the students' academic backgrounds, their levels of mathematical knowledge, and their plans for their future careers. Still, all students shared their joy of doing mathematics.

Publications

"Ramsey Theory Outreach" includes publications related to some of the Ramsey related topics accessible to high school and undergraduate students and the general public. 

Art

Here are several drawings inspired by Ramsey theory and people involved in Ramsey theory.

For example, the image on the Math Catcher Program logo, created by Ms. Bethani L'Heuruex of the Cree First Nation, was inspired by an edge-colouring of the complete graph on 14 vertices by 23 colours that avoids both monochromatic and rainbow complete subgraphs on four vertices. The colouring was constructed by Veselin Jungić, Tomas Kaiser, and Daniel Král in A note on edge-colourings avoiding rainbow K4 and monochromatic Km, The Electronic Journal Of Combinatorics 16 (2009), #N19.

The art presented here is the outcome of the collaboration between Veselin Jungić and Bethani L'Heureux, Listiarini Listiarini, Nicole Oishi, Kyra Pukanich, and Simon Roy.
