DIMAG hosted the “5th East Asia Workshop on Extremal and Structural Graph Theory” in Seoul
From November 27 to November 31, 2025, the IBS Discrete Mathematics Group hosted the 5th East Asia Workshop on Extremal and Structural Graph Theory in Seoul. 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 city.
