On August 18, 2026, Jinyoung Park (박진영) from NYU gave a talk at the Discrete Math Seminar on a reformulation of the Discrete Convexity Conjecture of Talagrand. The title of her talk was “A reformulation of Talagrand’s Discrete Convexity Conjecture“.
The IBS discrete mathematics group welcomes Dr. Daniel McGinnis, a new research fellow at the IBS Discrete Mathematics Group from August 16, 2026. He received his Ph.D. from the University of Iowa under the supervision of Prof. Shira Zerbib in 2024 and was subsequently a postdoctoral researcher at Princeton University. He is interested in combinatorics, discrete geometry, and combinatorial topology.
About 100 people attended the 2026 Summer School on Combinatorics and Algorithms from August 10 to August 14, 2026, held at KAIST. Daniel Dadush from CWI and Magnus Wahlström from the Royal Holloway, University of London gave lectures. This school was organized by Jungho Ahn (Inha University), Eun Jung Kim (KAIST / IBS / CNRS), Eunjin Oh (POSTECH), and Sang-il Oum (IBS Discrete Mathematics Group).
On August 7, 2026, Hyunwoo Lee (이현우) from KAIST and IBS Extremal Combinatorics and Probability Group gave a talk at the Discrete Math Seminar on a recent super-exponential lower bound for the multicolor triangle Ramsey number by OpenAI. The title of his talk was “A super-exponential lower bound construction for the multicolor triangle Ramsey problem discovered by OpenAI“.
On August 5, 2026, Meike Hatzel from TU Darmstadt gave a talk at the Discrete Math Seminar on a structural characterization of digraphs not immersing a cylindrical grid. The title of her talk was “Directed tree-cutwidth and immersions“.
On August 4, 2026, Tomohiro Koana from University of Tokyo gave a talk at the Discrete Math Seminar on a single-exponential fixed-parameter algorithm for enlarging a subgraph with at most k edges to make a 2-connected subgraph of a given graph. The title of his talk was “A Single-Exponential FPT Algorithm for 2-Vertex-Connectivity Augmentation“.
The IBS discrete mathematics group welcomes Dr. Olga Medrano Martín del Campo, a new research fellow at the IBS Discrete Mathematics Group from August 1, 2026. She received her Ph.D. from the University of Chicago under the supervision of Prof. Maryanthe Malliaris. She is interested in Learning in Theoretical Computer Science and connections to Logic and Combinatorics.
The IBS Discrete Mathematics Group welcomes Rifakat Alim Rashkee, a new graduate student of the Discrete Mathematics Group from August 1, 2026. He received his B.S. degree from KAIST and entered the Department of Mathematical Sciences at KAIST as a graduate student on March 2026. His advisor is Sebastian Wiederrecht.
