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.

2020 Combinatorics Workshop (2020 조합론 학술대회) was held on August 24 online
On August 24, Monday, the 2020 Combinatorics Workshop (2020 조합론 학술대회) was held online due to the COVID-19 pandemic. This local workshop series began in 2004 and has been continued to be one of the biggest annual gathering of people in combinatorics located in Korea. Due to the COVID-19 pandemic, it has been reduced to a one-day online conference on Zoom. It was hosted by Kyung Hee University and IBS Discrete Mathematics Group.
The workshop website: https://cw2020.combinatorics.kr
There were 5 invited speakers.
- Sejeong Bang (방세정), Yeungnam University, Geometric distance-regular graphs
- Ringi Kim (김린기), KAIST, Decomposing planar graphs into graphs with degree restrictions
- Sangwook Kim (김상욱), Chonnam National University, Combinatorics of lattice path matroid polytopes

2020 Combinatorics Workshop
Combinatorics Workshop (조합론 학술대회) is the biggest annual conference in combinatorics in Korea. It was firstly held in 2004 by the Yonsei University BK21 Research Group. It has been advised by the committee of discrete mathematics of the Korean Mathematical Society since 2013. The aim of this workshop is to bring active researchers with different backgrounds to discuss recent and prospective advances in combinatorics and related areas.
Originally, we planned an offline workshop. However, COVID 19 is more spreading and many participants are worried about attending an offline conference. So the schedule and venue are changed as an online workshop with Zoom. I hope that all participants generously understand this sudden change.
