Claude Sabbah wins Frontiers of Science Award

An initiative of the International Congress of Basic Science (ICBS), the Frontiers of Science Award honors fundamental and applied research in mathematics, physics, theoretical computer science and information science that represents a significant advance in these fields.

Claude Sabbah, CNRS Emeritus Research Director at CMLS, was honored for two of his recently published works. This renowned mathematician works in the field of differential equation systems applied to the study of singularities produced by polynomial equations, which is part of what is known as algebraic geometry.

The first prize-winning paper, in collaboration with Luisa Fiorot (University of Padua) and Teresa Monteiro Fernandes (University of Lisbon), analyzes the possible deformations of some of these systems of differential equations and produces new ways of controlling them using a method that dates back to the 19th century. This work follows in the footsteps of Masaki Kashiwara, who has just been awarded the Abel Prize 2025.

The second prize-winning paper, in collaboration with Javier Fresán (Sorbonne University) and Jeng-Daw Yu (National Taipei University), solves an arithmetical question raised in the physical sciences based on Feynman integral calculations. Using the tools developed by mathematicians following the proof of Fermat's theorem, this question is reduced in the article to a problem concerning certain systems of differential equations, which is also solved.

Frontiers of Science Award are supported by the City of Beijing and the Yanqi Lake Beijing Institute of Mathematical Sciences and Application (BIMSA).
