Incidence toric ideals and three-point functions
In this seminar talk, Barbara Betti from Otto-von-Guericke-Universität Magdeburg explores the ideal of algebraic relations among 3-point functions from a combinatorial and topological perspective. She situates the problem within incidence toric ideals associated with incidence matrices of t-subsets contained in k-subsets of n elements, whose generators can be interpreted as null t-designs and bala
