On January 3, 2025, Huy Tuan Pham from the Institute for Advanced Study and the Clay Mathematics Institute gave a talk at the Discrete Math Seminar on combinatorial methods for problems on additive combinatorics and random Cayley graphs. The title of his talk was “Random Cayley graphs and Additive combinatorics without groups“.
On December 23, 2024, Zixiang Xu (徐子翔) from the IBS Extremal Combinatorics and Probability Group gave a talk at the Discrete Math Seminar on using linear algebra to prove stability results in extremal set theory. The title of his talk was “Multilinear polynomial methods and stability results on set systems“.
On December 17, 2024, Joonkyung Lee (이준경) from Yonsei University gave a talk on using Lorentzian polynomials to prove a non-trivial upper bound on the number of graph homomorphisms at the Discrete Math Seminar. The title of his talk was “Counting homomorphisms in antiferromagnetic graphs via Lorentzian polynomials“.
On December 13, 2024, Jun Gao (高峻) from the IBS Extremal Combinatorics and Probability Group gave a talk at the Discrete Math Seminar on the maximum sum of the p-th power of degrees in a hypergraph without fixed subhypergraphs. The title of his talk is “Phase transition of degenerate Turán problems in p-norms“.
On December 3, 2024, Yulai Ma from Paderborn University gave a talk on the existence and non-existence of many disjoint perfect matchings in regular graphs with various edge-connectivity conditions at the Discrete Math Seminar. The title of his talk was “Pairwise disjoint perfect matchings in regular graphs“.
Due to a technical issue, some parts of the video were not properly recorded.
On November 26, 2024, Eng Keat Hng from the IBS Extremal Combinatorics and Probability Group gave a talk on characterizing fractionally isomorphic graphons in terms of the Galton-Watson branching process. The title of his talk was “Graphon branching processes and fractional isomorphism“.
The IBS Discrete Mathematics Group had the “2024 DIMAG Internal Workshop” at the Lahan Hotel of Jeonju on November 19-23, 2024. Participants include almost all current members of DIMAG, Sebastian Wiederrecht and Eunjung Kim from KAIST, Minki Kim from GIST, Cheolwon Heo and Jungho Ahn from KIAS, Eun-Kyung Cho from Hanyang University, Niloufar Fuladi from INRIA, and Noleen Köhler from the University of Leeds. Every participant presented open problems and had active discussions.
On November 20, 2024, Songji Chae (채송지) received the 2022 Outstanding Staff Award (우수직원상) from the IBS president. Congratulations!
On November 12, 2024, Karim Adiprasito from the Jussieu Institute of Mathematics, Paris Rive Gauche gave a talk at the Discrete Math Seminar on Ehrhart theory and the unimodality. The title of his talk was “Ehrhart theory revisited: Algebraic aspects, unimodality and more“.
The IBS Discrete Mathematics Group has an opening for the 1 IBS Young Scientist Fellowship.
With the vision of “Making discoveries for humanity and society,” the Institute for Basic Science (IBS) was founded in 2011 by the Korean government to promote basic science in Korea. To date, IBS operates 32 Research Centers which have been yielding outstanding results in various research fields.
The IBS started to select Young Scientist Fellow (YSF) in 2016 to play an active role in fostering the next generation of basic science leaders. This program offers young scientists opportunities to conduct independent research with state-of-the-art research infrastructure of the IBS and to grow on the basis of research collaborations with leading researchers.
We hope that the YSF program serves as a stepping stone for our researchers to mature into leading researchers in basic science.
Discrete Mathematics Group has an opening. Budget: Up to KRW 180 million per year.
