Forum Numerica - Thi Ha Duong PHAN: Complex Systems: On Certain Modeling and Algorithm Problems



Many complex systems can be modeled using very large graphs. These graphs exhibit qualities of robustness, randomness, dynamics, and distinctiveness when compared to others, yet they share certain crucial common properties. To analyze the behavior of complex systems, researchers aim to comprehend the fundamental characteristics of these extensive graphs and generate them randomly in a way that mirrors real complex systems. Additionally, complex systems research addresses essential issues, such as the partitioning of a population into communities where each community displays common behavior and shared interests. In this presentation, we will explore the modeling of large graphs and discuss algorithms for the problem of community detection.

PHAN Thi Ha Duong is an Associate Professor at the Institute of Mathematics, the Academy of Sciences and Technologies of Vietnam. Her research areas include complex systems, enumerative combinatorics, and algorithms.

Phan Thi Ha Duong obtained her doctoral degree in 1999, followed by a Doctor of Habilitation in 2017 at the University of Paris 7. She has been a Maitre de Conférences at the University of Paris 7 since 1999. In 2005, she returned to Vietnam and then became the head of the "Mathematical Foundations for Computer Science" department from 2010 to 2022. She also served as the Vice-Director of the International Center for Research and Postgraduate Training in Mathematics under the auspices of UNESCO, collaborating with numerous French universities, including Paris 6, ENS de Lyon, and the University of the Côte d'Azur, among others.

She has been a visiting professor and has presented seminars at the University of Paris 6 (2019, 2016, 2011, 2009, 2008), the École Normale Supérieure of Lyon (2014, 2011), the École Polytechnique of Paris (2011), the University of Paris 7 (2017, 2011, 2009), the University of Nice (2009), the University of La Rochelle (2008), and more. She has supervised five doctoral theses and twenty master's theses, approximately one-third of which were in collaboration with French colleagues.
