IBS Discrete Mathematics Group (이산수학그룹)


On December 1st, 2018, IBS Discrete Mathematics Group (DIMAG) was established in the Institute for Basic Science (IBS), a research institution funded by the South Korean government. DIMAG is located in the  headquarters of the IBS in Daejeon, Korea. It is led by Prof. Sang-il Oum, who is the CI (Chief Investigator) and belongs to the Center for Mathematical and Computational Sciences.


  • To carry out top-class research in discrete mathematics, graph theory, and algorithms.
  • To facilitate collaborations with researchers in related fields.
  • To organize seminars, workshops, conferences and schools actively to encourage sharing results, creating ideas and promoting future researchers.

Andreas Holmsen presented his work on an extremal problem on hypergraphs on March 12 at the discrete math seminar

Andreas Holmsen from KAIST gave a talk at Discrete Math Seminar on March 12, 2019 under the title “large cliques in hypergraphs with forbidden substructures.” His work extended a result of extremal graph theory due to Gyárfás, Hubenko, and Solymosi, answering a question of Erdős to hypergraphs and has interesting consequences in topological combinatorics and …

DIMAG had its first workshop “2019-1 IBS Workshop on Graph Theory”

DIMAG had its first workshop “2019-1 IBS Workshop on Graph Theory” on February 11 and 12, 2019. There were 6 invited talks — Jeong Han Kim (KIAS), Cory T. Palmer (Univ. of Montana), Martin Balko (Charles Univ.), Dong Yeap Kang (KAIST), Boram Park (Ajou Univ.), and Dániel Gerbner (Alfréd Rényi Institute of Mathematics). We would …
