The annual conference on Combinatorics Workshop (조합론 학술대회) was begun in 2004 by the Yonsei University BK21 Research Group. Since 2013, this workshop has been advised by the committee of discrete mathematics of the Korean Mathematical Society. This year it will take place at GIST in Gwangju on September 30 - October 1, 2022.
The aim of this workshop is to bring together active researchers with different backgrounds to discuss recent and prospective advances in combinatorics and related areas.
Starting in the afternoon of September 30 (Friday) and ending in the afternoon of October 1 (Saturday).
There will be 4 invited talks and 9 contributed talks.
Using English is recommended if there are non-Korean participants in the audience.
It will be an offline meeting.
