O-joung Kwon (권오정) gave a talk on upper bounds of twin-width and reduced-bandwidth of planar graphs and H-minor-free graphs at the Discrete Math Seminar

On January 25, 2022, O-joung Kwon (권오정) from the Incheon National University / IBS Discrete Mathematics Group gave a talk at the Discrete Math Seminar on upper bounds of the twin-width and reduced-bandwidth of planar graphs and H-minor-free graphs at the Discrete Math Seminar. The title of his talk was “Reduced bandwidth: a qualitative strengthening of twin-width in minor-closed classes (and beyond)“.

Seunghun Lee (이승훈) gave a talk on the transversal number and the chromatic number of hypergraphs consisting of facets of a simplicial sphere at the Discrete Math Seminar

On January 4, 2022, Seunghun Lee (이승훈) from the Binghamton University gave a talk at the Discrete Math Seminar on the transversal number and the chromatic number of hypergraphs whose edges are facets of a simplicial sphere. The title of his talk was “Transversals and colorings of simplicial spheres“.
