On May 12, 2020, Eun Jung Kim (김은정) from LAMSADE, CNRS presented a talk on her recent work on the twin-width. The title of her talk was “Twin-width: tractable FO model checking“. She is visiting the IBS discrete mathematics group from May 12 for about 4 months.
Due to COVID-19, it was decided to postpone the following two workshops to be held in August, 2020 at IBS by the organizers of each workshop.
On April 28, 2020, Seunghun Lee (이승훈) from KAIST presented a talk on the topological property of the non-matching complex, that is a simplicial complex consisting of subgraphs on the same vertex set having no matching of size k and its application to the rainbow matching problem of graphs. The title of his talk is “Leray numbers of complexes of graphs with bounded matching number“.
On April 21, 2020, Sang-il Oum gave a survey talk on vertex-minors of graphs at the discrete math seminar. The title of his talk was “survey on vertex-minors“.
On April 14, 2020, Casey Tompkins from IBS discrete mathematics group gave a talk on the saturation version of the problems related to the Erdős-Szekeres theorem on convex k-gons, sequences, and posets. The title of his talk is “Saturation problems in the Ramsey theory of graphs, posets and point sets“.
On April 7, 2020, Pascal Gollin from the IBS Discrete Mathematics Group presented his work on the relation between the packing of edge sets intersecting all directed cuts in some class B and the maximum size of a minimal nonempty directed cut in B, motivated by Woodall’s conjecture. The title of his talk is “Disjoint dijoins for classes of dibonds in finite and infinite digraphs“.
IBS is inviting applications for Young Scientist Fellowship. The application due is May 31, 2020. To be eligible, one should be within 7 years of obtaining a Ph.D. or under the age of 40 with a Ph.D. (born no earlier than 1 January 1980).
This is a full-time research position and the appointment is for 3 years with a possible 2-year extension depending on the performance review results. (If a current IBS researcher is appointed as YSF, then the maximum duration is 3 years.)
Please check https://www.ibs.re.kr/ysf/ and https://dimag.ibs.re.kr/ysf/ for more information.
IBS DIMAG will also have a few openings. The successful candidate will join the discrete mathematics group with his or her own separate research budget.
The IBS Discrete Mathematics Group (DIMAG) in Daejeon, Korea invites applications for several postdoctoral research fellowship positions.

DIMAG is a new research group that was established in December 1, 2018 at the Institute for Basic Science (IBS), led by Prof. Sang-il Oum. DIMAG is located at the headquarters of the Institute for Basic Science (IBS) in Daejeon, South Korea, a city of 1.5 million people.
Successful candidates for postdoctoral research fellowship positions will be new or recent Ph.D.’s with outstanding research potential in all fields of discrete mathematics with emphasis on structural graph theory, extremal graph theory, combinatorial optimization, matroid theory, or fixed-parameter tractable algorithms.
These non-tenure-track appointments are for two or three years, and the starting salary is no less than KRW 57,000,000. The appointment is one time renewable up to 5 years in total contingent upon the outstanding performance of the researcher.
These are purely research positions and research fellows will have no teaching duties.
A complete application packet should include:
For full consideration, applicants should email items 1, 2, 3, and 4 and arrange their recommendation letters emailed to dimag@ibs.re.kr by April 26, 2020, Sunday. Recommendations letters forwarded by an applicant will not be considered.
DIMAG encourages applications from individuals of diverse backgrounds.
For Korean citizens who have not yet completed their military duty: IBS는 병역특례지정기관입니다. IBS is a designated institute for alternative military service.
On March 31, 2020, Ringi Kim (김린기) from KAIST presented his work on the strong clique number of graphs with Eun-Kyung Cho, Ilkyoo Choi, and Boram Park. The title of his talk is “The strong clique number of graphs with forbidden cycles“.
Due to COVID-19, the organizers decided to postpone the conference “Seymour is Seventy” to be held in Lyon, France, June 15-19, 2020. We hope to run a similar event in the summer of 2021 instead. Specific decisions on the dates are to be made when the situation clarifies.
