Michael Savery gave an online talk on finding a graph of huge chromatic number such that every induced subgraph of large chromatic number has an induced copy of a fixed subgraph at the Virtual Discrete Math Colloquium

On April 27, 2022, Michael Savery from the Oxford University gave an online talk at the Virtual Discrete Math Colloquium on finding a graph of huge chromatic number such that every induced subgraph of large chromatic number has an induced copy of a fixed subgraph at the Virtual Discrete Math Colloquium. The title of his talk was “Induced subgraphs of induced subgraphs of large chromatic number“.

Hong Liu is appointed as the CI of the new group, “IBS Extremal Combinatorics and Probability Group (ECOPRO)” as of April 1

On April 1, 2022, Hong Liu from the University of Warwick is appointed as the Chief Investigator to lead a new group, the IBS Extremal Combinatorics and Probability Group (ECOPRO), in the Center for Mathematical and Computational Sciences. To enhance our collaboration, the IBS Discrete Mathematics Group will move to the 3rd floor of the theory building on April 19-21 to share the space with the Extremal Combinatorics and Probability Group.
