On May 26, 2020, Hong Liu from University of Warwick presented a talk on his recent work describing approximate structures of an n-vertex m-edge graph minimizing the number of cliques of size k. The title of his talk was “Asymptotic Structure for the Clique Density Theorem”.
On May 19, 2020, O-joung Kwon (권오정) from Incheon National University and IBS Discrete Mathematics Group presented a survey talk on the MIM-width of graphs. The title of his talk was “Mim-width: a width parameter beyond rank-width“.
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.
- 2020 IBS Workshop on Extremal and Probabilistic Combinatorics (Initially scheduled on August 24-28, 2020)
- Nonlinear Algebra in Daejeon (Initially scheduled on August 4-13, 2020)
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 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 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.)
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:
- AMS standard cover sheet (preferred) or cover letter (PDF format)
- Curriculum vitae including a publication list (PDF format)
- Research statement (PDF format)
- Consent to Collection and Use of Personal Information (PDF file)
- At least 3 recommendation letters
For full consideration, applicants should email items 1, 2, 3, and 4 and arrange their recommendation letters emailed to firstname.lastname@example.org by April 26, 2020, Sunday. Recommendations letters forwarded by an applicant will not be considered.
DIMAG encourages applications from individuals of diverse backgrounds.
