Seunghun Lee (이승훈) gave a talk on order types realized by a point configuration whose extreme points are cocircular at the Discrete Math Seminar

On August 1, 2022, Seunghun Lee (이승훈), who is from the Binghamton University, and will be soon at the Hebrew University of Jerusalem, gave a talk at the Discrete Math Seminar on order types realized by a point configuration whose extreme points are cocircular. The title of his talk was “Inscribable order types“.

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“.

Seunghun Lee (이승훈) gave a talk on the complexes of subgraphs having no large matching at the Discrete Math Seminar

On April 28, 2020, Seunghun Lee (이승훈) from KAIST presented a talk on the topological property of the non-matching complex, that is a simplicial complex consisting of subgraphs on the same vertex set having no matching of size k and its application to the rainbow matching problem of graphs. The title of his talk is “Leray numbers of complexes of graphs with bounded matching number“.
