Supported by the IBS Discrete Mathematics Group, the workshop brings together Korean graduate and undergraduate students and postdoctoral researchers studying combinatorics. Its aim is to promote interaction among young researchers, share research interests, and establish a foundation for future collaborative research.
The program included invited talks, contributed talks, and sessions for sharing and discussing open problems.
This workshop continues the Korean Student Combinatorics Workshop series from 2024.
The workshop was organized by the following four students:
The 2026 Workshop on Topological Combinatorics was successfully held at Gwangju Institute of Science and Technology (GIST) from June 28 to July 11, 2026. The workshop was organized by Andreas Holmsen (KAIST & IBS DIMAG), Jinha Kim (Chonnam National University & IBS DIMAG), and Minki Kim (GIST), with support from GIST, IBS Discrete Mathematics Group (DIMAG), and the National Research Foundation of Korea (NRF).
This workshop is the fifth in the international series on topological combinatorics initiated by Ron Aharoni. It brought together researchers working in topological combinatorics, discrete geometry, algebraic topology, geometric transversal theory, topological methods in combinatorics, and related areas. The first week consisted of invited lectures and research presentations, while the second week was devoted to collaborative research and open problem discussions.
More than 60 researchers from Korea and overseas participated during the two-week program. Participants represented a wide range of institutions, including IBS DIMAG, KAIST, GIST, Chonnam National University, Ajou University, DGIST, KIAS, Princeton University, Carnegie Mellon University, University of Waterloo, Charles University, Université Paris Cité, École nationale des ponts et chaussées, Arizona State University, Iowa State University, Binghamton University, UNAM, MPI-CBG Dresden, Singapore University of Technology and Design, and several other universities and research institutes.
The scientific program featured invited lectures by leading researchers together with short research presentations covering recent developments in topological combinatorics and its interactions with geometry, topology, algebra, and combinatorics. The collaboration week provided participants with ample opportunities to initiate new research projects and strengthen existing international collaborations.
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.
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.
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.
Invited Speakers
Jiangdong Ai (Nankai University, China)
Ilkyoo Choi (Hankuk University of Foreign Studies, Korea)
The 2023 Vertex-Minor Workshop was held from October 15, 2023 to October 20, 2023 at SONO Belle Jeju in Korea. This workshop aimed to foster collaborative discussions and explore the various aspects of vertex-minors, including structural theory and their applications. There were 17 participants from Korea, Italy, UK, Australia, Japan, and China and participants had great time to discuss open problems related to the vertex-minors of graphs.
Talks
October 16: Sang-il Oum, Survey of vertex-minors
October 17: O-joung Kwon, The grid theorem for vertex-minors
October 17: James Davies, Vertex-minors and preparing graph states
October 17: Paul Wollan, Flat-wall theorem for vertex-minors
The MATRIX-IBS Workshop “Structural Graph Theory Downunder III” was held from April 17, 2023 to April 23, 2023 at Creswick, Victoria, Australia. This program is supported by MATRIX and the Discrete Mathematics Group (DIMAG) of the Institute for Basic Science (IBS, Korea). MATRIX is a residential research institute for the mathematical sciences in Australia.
The IBS Discrete Mathematics Group (DIMAG) had its third internal workshop with the new IBS Extremal Combinatorics and Probability Group (ECOPRO) at the Yeosu Expo UTOP Marina Hotel & Resort under the name “The 2022 DIMAG-ECOPRO Joint Internal Workshop” on October 31-November 3, 2022. Participants include almost all current members of DIMAG and ECOPRO, Minki Kim from GIST, Cheolwon Heo from Sungkyunkwan University, Eun-Kyung Cho from Hankuk University of Foreign Studies, and Semin Yoo from KIAS. Every participant presented open problems and had active discussions.
