The IBS Discrete Mathematics Group had its first “DIMAG internal workshop” at Jeonju Lahan Hotel located in Jeonju Hanok Village on November 16-18, 2020. Participants include almost all current members of DIMAG and Jaehoon Kim from KAIST, and Hong Liu from University of Warwick. Every participant had a chance to present their current research problems informally.

From October 31 to November 4, 2019, IBS discrete mathematics group hosted the 2nd East Asia Workshop on Extremal and Structural Graph Theory in Jeju. It is a workshop to bring active researchers in the field of extremal and structural graph theory, especially in the East Asia such as China, Japan, and Korea. Participants have great chance to discuss recent progress in graph theory, interesting open problems, finding new potential collaborators, and exploring the beautiful island.
