In Memoriam John Conway

John Horton Conway FRS (26 December 1937 – 11 April 2020) was an English mathematician active in the theory of finite groups, knot theory, number theory, combinatorial game theory and coding theory. He also made contributions to many branches of recreational mathematics, most notably the invention of the cellular automaton called the Game of Life.

Game of Life is one of the early examples of a cellular automaton. His initial experiments in that field were done with pen and paper, long before personal computers existed.

Since the game was introduced by Martin Gardner in Scientific American in 1970, it has spawned hundreds of computer programs, web sites, and articles. It is a staple of recreational mathematics. From the earliest days, it has been a favorite in computer labs, both for its theoretical interest and as a practical exercise in programming and data display. Conway used to hate the Game of Life — largely because it had come to overshadow some of the other deeper and more impo…

Online colloquia series

In the time of social distancing, these colloquia/seminars are available digitally:

weekly online combinatorics seminar aimed at graduate students and am excited to announce that the seminar is now official! Here is the website: Talks will generally be 1:00-2:00 on Wednesday and all are welcome to attend (although first priority to present will be given to grad students and postdocs). If you'd like to join the GOCC googlegroup which will allow you to get emails and zoom links for future talks, please email That's also where you can let me know if you'd like to sign up to give a talk.

Conference Postponement, 32nd Cumberland

Dear colleagues,
In light of the current coronavirus situation, we have to cancel the 32nd Cumberland Conference on Combinatorics Graph Theory and Computing, which we had planned to hold at William & Mary in Williamsburg, Virginia on May 23-24, 2020.
This is a very sad decision for us to make.  We were well-prepared to have a great conference here in Virginia.  Four outstanding scholars (Daniel Kral, Blair Sullivan, Douglas West, Yufei Zhao) had agreed to be our plenary speakers (
32nd Cumberland Conference on Combinatorics, Graph Theory, and Computing 32nd Cumberland Conference on Combinatorics, Graph Theory, and Computing: May 23-24, 2020 College of William & Mary Williamsburg, VA 23185 ). Our college had provided generous support and we had also requested funding from NSF to support the travel of more junior researchers (Zi-Xia Song and Rong Luo were very kind to share with us their previous NSF proposa…

In Memoriam Robin Thomas

Thomas received his doctorate in 1985 from Charles University in Prague, Czechoslovakia (now the Czech Republic), under the supervision of Jaroslav Nešetřil. He joined the faculty at Georgia Tech in 1989, and became a Regents' Professor there, briefly serving as the department Chair.
Thomas was awarded the Fulkerson Prize for outstanding papers in discrete mathematics twice, in 1994 as co-author of a paper on the Hadwiger conjecture, and in 2009 for the proof of the strong perfect graph theorem. In 2011 he was awarded the Karel Janeček Foundation Neuron Prize for Lifetime Achievement in Mathematics. In 2012 he became a fellow of the American Mathematical Society. He was named a SIAM Fellow in 2018.In 2016 he received the Class of 1934 Distinguished Professor Award, the highest honor for a professor at Georgia Tech.
On March 26, 2020, he lost his twelve-year struggle against Amyotrophic Lateral Sclerosis.

Postponement of Combinatorics 2020

With great regret I announce that, due to the Coronavirus emergency, the organizers have decided that the Conference "Combinatorics 2020" will NOT take place 1-5 June 2020.

The event is rescheduled for 31 May - 4 June 2021, so exactly one year ahead, turning the Conference into a "Combinatorics 2021" at Mantua (Italy).

In Memoriam Vera Pless

Vera Pless, noted coding theorist, passed away peacefully in her home March 2, 2020.

Vera Stepen was born on March 5, 1931 on Chicago's west side to a Russian Jewish immigrant family. As a teenager, she was more interested in playing the cello than in mathematics, but she left high school two years early to go to the University of Chicago, and finished her studies there in three years. Inspired by Irving Kaplansky to study abstract algebra, she stayed at the university for a master's degree, which she earned in 1952 not long after marrying her husband, a high-energy experimental physicist. She began working in physics at the University of Chicago, but soon won a fellowship to study at Northwestern University. Her husband became a professor at the Massachusetts Institute of Technology; Pless moved with him to Massachusetts, where she completed her doctorate from Northwestern in 1957 under the supervision of Kaplansky's student Alex F. T. W. Rosenberg, with the Dissertation: Qu…

2020 Annual General Meeting Minutes

The meeting was called to order March 11, 2020 at 11:03am during the designated session of the SouthEastern International Conference on Combinatorics, Graph Theory, and Computing.

Due to the COVID-19 outbreak, Dalibor and Sarah performed feats of ventriloquism never to be seen again using only their wits and some prepared slides.

ICA Executive (2019-2020) _ The ICA was established in 1990 by Ralph Stanton for the purpose of promoting the development of combinatorics and of encouraging publications and conferences in combinatorics and its applications. _ The three most important functions of the ICA are: _ publishing the Bulletin of the ICA _ supporting conferences, and _ awarding medals and honorary fellowships.
_ All three of these functions have been addressed and improved in recent years, thanks to the efforts of many people (details on later slides). Doug Stinson President 2019-2022 Dalibor Froncek Vice-president 2019-2022 …
