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.
From February 10 to 12, 2025, the second week of the IBS-DIMAG Winter School on Graph Minors took place at IBS. This week, Maximilian Gorsky from the IBS Discrete Mathematics Group gave lectures on classifying society using a structure called transaction meshes.
The IBS-DIMAG Winter School on Graph Minors is taking place at IBS every Monday, Tuesday, and Wednesday over a three-week period, beginning on February 3, 2025. Sebastian Wiederrecht (KAIST) and Maximilian Gorsky (IBS Discrete Mathematics Group) are giving lectures. In the first week, the topics covered included the two-paths theorem, the flat wall theorem, and various results on societies, transactions, and vortices.
The IBS Discrete Mathematics Group had the “2024 DIMAG Internal Workshop” at the Lahan Hotel of Jeonju on November 19-23, 2024. Participants include almost all current members of DIMAG, Sebastian Wiederrecht and Eunjung Kim from KAIST, Minki Kim from GIST, Cheolwon Heo and Jungho Ahn from KIAS, Eun-Kyung Cho from Hanyang University, Niloufar Fuladi from INRIA, and Noleen Köhler from the University of Leeds. Every participant presented open problems and had active discussions.
On November 11, 2024, the IBS-DIMAG Workshop on Topology and Combinatorics was held at IBS, which had 7 invited speakers. Semin Yoo was the organizer.
Invited Speakers
The 2024 Combinatorics Workshop (2024 조합론 학술대회) was held from August 28, 2024 to August 30, 2024 at Chungbuk National University, Cheongju. Combinatorics Workshop (조합론 학술대회) is an annual conference for researchers in combinatorics and related areas in Korea, started in 2004. There were five invited talks and ten contributed talks.
The 2024 Workshop on (Mostly) Matroids was held at the IBS Science Culture Center from August 19 to August 23, 2024. There were 41 talks. Videos are available.
The 2024 Korean Student Combinatorics Workshop (KSCW2024, 2024 조합론 학생 워크샵) was held in Gongju from July 29 to August 2, 2024. Sponsored by the IBS Discrete Mathematics Group, this event aims to provide a platform for Korean graduate students working on combinatorics and related areas to establish a foundation for collaborative research. It was organized by four students of KAIST/IBS: Donggyu Kim (김동규), Seokbeom Kim (김석범), Seonghyuk Im (임성혁), and Hyunwoo Lee (이현우). The workshop featured two invited talks by Semin Yoo (유세민) and Jungho Ahn (안정호), as well as open problem sessions followed by ample time for joint work.
The IBS-DIMAG Workshop on Combinatorics and Geometric Measure Theory was held at IBS from July 14 to July 19, 2024. There were 23 talks, including plenary talks by János Pach (Rényi Institute of Mathematics) and Pertti Mattila (University of Helsinki) and invited talks by Izabella Łaba (University of British Columbia), Hong Wang (NYU), and Cosmin Pohoata (Emory University).
From November 1 to November 5, 2023, the 3rd East Asia Workshop on Extremal and Structural Graph Theory was held in Okinawa, Japan. It is a workshop to bring active researchers in the field of extremal and structural graph theory, especially in East Asia such as China, Japan, and Korea. Participants have a great chance to discuss recent progress in graph theory, interesting open problems, and finding new potential collaborators. The previous workshops were held in Shanghai (2018) and Jeju (2019). The IBS Discrete Mathematics Group was the main sponsor of the workshop.
