KdVI Discrete Mathematics Seminars
The weekly seminar on discrete mathematics at the Korteweg-de Vries Institute for Mathematics is organized by Vincent Schmeits and I. The seminar is currently on break for the summer. Talks can be attended remotely via zoom, on request. Anyone interested in attending or contributing a talk can contact Wout Moltmaker for more information via [w.c.moltmakerATuva.nl].
