Séminaire

Date : 30 septembre 2025 11:00 - Salle :salle A002 Complex Networks and Community Detection via Random Walks Pr. Phan Thi Ha Duong - Institut de Mathématiques, Académie des Sciences du Vietnam

Our research focuses on complex systems. First, I will present some fundamental properties of very large graphs that serve as models for such systems. Then, I present the problem of community detection, which has been extensively studied using various methods, predominantly in the setting of undirected graphs. Our approach is based on random walks, which not only enhance well-known algorithms for undirected graphs but also allow us to extend these results to the directed case.

Part 2. Ideas of collaboration

In the second part of my presentation, I will introduce the international cooperation frameworks to which we contribute. These include the International Centre for Research and Training in Mathematics (ICRTM), operating under the auspices of UNESCO, and the International Research Laboratory France–Vietnam in Mathematics and its Applications (IRL FVMA) and the Master program at USTH (Vietnam - France University). All initiatives foster long-term collaborations, support capacity building, and promote excellence in mathematical and computer science researchs.
