On February 27, 2024, Jie Han (韩杰) from the Beijing Institute of Technology gave a talk at the Discrete Math Seminar on the complexity of deciding the existence of a perfect matching in k-uniform hypergraphs under various degree conditions. The title of his talk was “Perfect matchings in dense uniform hypergraphs“. Jie Han will stay at IBS for two months.
Sebastian Wiederrecht gave a talk on the 1/4-integral Erdős-Pósa property of even directed cycles at the Discrete Math Seminar
On February 14, 2024, Sebastian Wiederrecht from the IBS Discrete Mathematics Group gave a talk at the Discrete Math Seminar, showing that the even directed cycles have the 1/4-integral Erdős-Pósa property. The title of his talk was “Packing even directed circuits quarter-integrally“.

Welcome Prof. Andreas Holmsen from KAIST, a new Visiting Research Fellow in the IBS Discrete Mathematics Group
The IBS Discrete Mathematics Group welcomes Prof. Andreas Holmsen from the Department of Mathematical Sciences, KAIST, Daejeon, Korea. He will visit the IBS Discrete Mathematics Group for 1 year from February 1, 2024 during his sabbatical leave from KAIST. He received his Ph.D. from the University of Bergen in 2004 under the supervision of Prof. Helge Tverberg and was at the University of Bergen, New York University, City College of New York before coming to KAIST.
