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“.
