Discrete Mathematics Group

IBS Discrete Mathematics Group (DIMAG) is one of the research groups in the Center for Mathematical and Computational Sciences in the Institute for Basic Science, led by its Chief Investigator  Sang-il Oum. Established in December 2018, DIMAG is located on the 3rd floor of the Theory Building of the IBS HQ, Daejeon, South Korea with the IBS Extremal Combinatorics and Probability Group.

기초과학연구원 이산수학그룹 (IBS Discrete Mathematics Group, DIMAG)은 기초과학연구원(IBS) 수리 및 계산 과학 연구단 내에 속한 연구 그룹 중 하나로, 엄상일 CI가 책임을 맡고 있습니다. 2018년 12월에 설립된 이산수학그룹은 대전 IBS 본원 이론동 3층에 기초과학연구원 극단 조합 및 확률 그룹(IBS Extremal Combinatorics and Probability Group)과 함께 위치하고 있습니다.
