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.

Sebastian Wiederrecht gave lectures during the third week of the IBS-DIMAG School on Graph Minors

From February 17 to 19, 2025, the third and last week of the IBS-DIMAG Winter School on Graph minors took place at IBS with lectures by Sebastian Wiederrecht from KAIST. He gave lectures on explaining tangles, sketching the proof of the Graph Minor Structure Theorem of Robertson and Seymour, and presenting the key idea of improving the bounds (for vortices and apices) to polynomials.

This school was held for three consecutive weeks from February 3, 2025.
