On November 25, 2025, Péter Pál Pach from the Budapest University of Technology and Economics gave a talk at the Discrete Math Seminar on the maximum set of positive integers that avoids having any product of k elements equal to a d-th power. The title of his talk was “Product representation of perfect cubes“.
On November 18, 2025, Fedor Noskov from MIPT, Russia gave a talk at the Discrete Math Seminar on hypergraph Turán-type problems and their connection to extremal set theory problems. The title of his talk was “Polynomial dependencies in hypergraph Turan-type problems“.

On November 4, 2025, Tim Hartmann and Ahemed Ghazy from CISPA Helmholtz Center for Information Security in Germany gave a talk at the Discrete Math Seminar on continuous graphs—a model obtained by replacing each edge of a graph with a unit interval to form a metric space, enabling continuous analogues of classical graph problems. The title of their talk was “Continuous Graphs – An Overview and a Coloring Problem“.
