On May 19, 2026, Xavier Goaoc from Université de Lorraine gave a talk at the Discrete Math Seminar on a tree decomposition of the chirotopes of a planar point set and its application to counting triangulations of a chirotope. The title of his talk was “A canonical tree decomposition for order types, and some applications“.
The IBS Discrete Mathematics Group welcomes Arnaud Patey, a new graduate student of the Discrete Mathematics Group from May 18, 2026 to July 17, 2026. He is a MS student at ENS Rennes.
On May 12, 2026, Benjamin Duhamel from ENS de Lyon gave a talk at the Discrete Math Seminar on characterizing forests F such that forbidding a biclique and an induced minor isomorphic to F implies bounded path-width. The title of his talk was “Excluding a forest induced minor“.
On May 6, 2026, Maximilian Gorsky from the IBS Discrete Mathematics Group gave a talk at the Discrete Math Seminar on a new algorithm for k-disjoint paths problem with an explicit running time. The title of his talk was “The Disjoint Paths Problem lies in the Oort cloud of algorithms“.
On April 28, 2026, Xin Wei (魏歆) from the IBS Extremal Combinatorics and Probability Group gave a talk at the Discrete Math Seminar on the maximum size of a t-perfect hash family over an alphabet of size q. The title of his talk was “Separating hash families with large universe“.
