Debsoumya Chakraborti gave a talk on the problem of maximizing the number of cliques in a graph of small maximum degree at the Discrete Math Seminar

On September 15, 2020, Debsoumya Chakraborti from the IBS Discrete Mathematics Group presented a talk on the extremal problem on the number of cliques in a graph of small maximum degree with a fixed number of edges. The title of his talk was “Maximum number of cliques in a graph with bounded maximum degree“.

Sebastian Siebertz gave a talk on recent approaches to combine model theoretic and graph theoretic tools to derive structural and algorithmic results for classes of (finite) graphs at the Virtual Discrete Math Colloquium

On September 10, 2020, Sebastian Siebertz from University of Bremen gave an online talk about recent attempts to combine the model theory to the theory of dense graphs at the Virtual Discrete Math Colloquium. The title of his talk was “Rank-width meets stability“.

Junguk Lee (이정욱) from KAIST gave an intensive lecture on the stability and NIP in the model theory at the Discrete Math Seminar for two days

On August 31 and September 1, 2020, Junguk Lee (이정욱) from KAIST gave a 6-hour-long talk on the model theory with the focus on the stability, NIP, and the VC dimension at the Discrete Math Seminar. The title of his talk was “a quick introduction to stability and NIP”. The part 1 “basics” and the part 2 “stability” were coved on August 31, for 1.5 hours each, and the part 3 “NIP” was covered on September 1 for 3 hours (10:30-11:30, 3:00-4:00, 4:10-5:10).

Welcome Jinha Kim (김진하) and Minki Kim (김민기), new members of IBS Discrete Mathematics Group

The IBS Discrete Mathematics Group welcomes Dr. Jinha Kim (김진하) and Dr. Minki Kim (김민기), new research fellows at the IBS Discrete Mathematics Group from September 1, 2020.

Jinha Kim (김진하) received his Ph.D. from the Department of Mathematics at Seoul National University in 2019 under the supervision of Prof. Woong Kook. Until recently, she was a postdoctoral fellow at Technion in Israel. She is interested in combinatorics, discrete geometry, topological combinatorics, and graph theory.

Minki Kim (김민기) received his Ph.D. from the Department of Mathematical Sciences at KAIST in 2018 under the supervision of Prof. Andreas Holmsen. Until recently, he was a postdoctoral fellow at Technion in Israel. He is interested in discrete geometry, topological combinatorics, and graph theory.
