Hyunwoo Lee (이현우) gave a talk on determining the matching polynomial of k-uniform hypergraphs from the list of all induced subhypergraphs of fixed size at the Discrete Math Seminar

On April 1, 2025, Hyunwoo Lee (이현우) from KAIST and IBS Extremal Combinatorics and Probability Group gave a talk at the Discrete Math Seminar on the problem of determinining the matching polynomial of k-uniform hypergraphs from the list of all induced subhypergraphs of fixed size. The title of his talk was “Reconstructing hypergraph matching polynomials“.

Michał T. Seweryn gave a talk on the existence of Kelly’s poset in a poset of sufficient large dimension with a planar cover graph at the Discrete Math Seminar

On March 18, 2025, Michał T. Seweryn from Charles University gave a talk at the Discrete Math Seminar showing that every poset of very large dimension with a planar cover graph has Kelly’s poset of large dimension. The title of his talk was “Dimension and standard examples in planar posets“.

Jang Soo Kim gave a talk on the maximum of the minimum number of generators to represent an element in a monoid of functions on a fixed finite set and its connection to the minimum feedback arc set of a tournament at the Discrete Math Seminar

On February 4, 2025, Jang Soo Kim (김장수) from Sungkyunkwan University gave a talk on the maximum of the minimum number of generators to represent an element in a monoid of functions on a fixed finite set and its connection to the minimum feedback arc set of a tournament at the Discrete Math Seminar. The title of his talk was “Longest elements in a semigroup of functions and Slater indices“.
