From June 26 to July 13, 2025, a delegation consisting of students of the MMF NSU Maxim Emelianov, Timofey Vasiliev, Wang Yifei, Ayana Ondar and Maxim Levashov took part in the International Summer School on Combinatorics. The event was held at the Three Gorges University of China. The scientific program of the school was focused on an in-depth study of the theory of symmetric functions, Kazhdan-Lustig polynomials, Newton polyhedra and Lorentz polynomials. The learning process was aimed at deep practical mastery of the material: as part of the classes, the participants actively engaged in scientific discussions with lecturers and colleagues, and at the end of the courses they successfully passed the exam, confirming a high level of knowledge. An important part of the school were the presentations of the participants themselves with their scientific reports, which were highly appreciated by both the Chinese students and the organizers.
In addition to intensive scientific work, the organizers prepared a rich cultural program for the participants, which allowed them to get to know the history and traditions of China better. It included a trip to the world's largest hydroelectric power station, the Three Gorges, excursions to a picturesque waterfall and history museums, as well as master classes in traditional handicrafts and cultural exchange events.
“It was an incredibly productive and inspiring trip. We had a unique opportunity to communicate in person with the authors of fundamental works,” shares his impressions first-year Master's student at the Faculty of Mathematics and Mechanics Maxim Yemelyanov. “The lectures on the theory of symmetric functions were especially valuable, demonstrating how a single mathematical apparatus allows us to solve, at first glance, completely different problems. This gave us a new vision and powerful tools for analyzing discrete structures. I am confident that the knowledge we gained will become a solid foundation for our further research, and the scientific contacts we established will open up new opportunities for cooperation.”
