Dr. Rémy Rodiac to receive the 2026 G. de B. Robinson Award

Ottawa, ON – The Canadian Mathematical Society (CMS) is pleased to announce that Dr. Rémy Rodiac (Université Côte d’Azur) is the recipient of the 2026 G. de B. Robinson Award. Dr. Rodiac is receiving this award for this paper “Stability conditions for mean-field limiting vorticities of the Ginzburg-Landau equations in 2D”, published in the Canadian Journal of Mathematics (77:6 [2025], pp. 2029-2060). The G. de B. Robinson Award was inaugurated to recognize the publication of excellent papers in the Canadian Journal of Mathematics (CJM), the Canadian Mathematical Bulletin (CMB), and, more recently, the Canadian Mathematical Communications (CMC), and to encourage the submission of the highest quality papers to these journals.

Dr. Rémy Rodiac is a mathematician specializing in calculus of variations and partial differential equations. His research focuses on the analysis of singularities and energy minimizations problems arising in physical models such as superconductivity, nonlinear elasticity, and Coulomb particle systems. He obtained his PhD in mathematics from Université Paris-Est in 2015 under the supervision of Dr. Laurent Hauswirth and Dr. Étienne Sandier. Dr. Rodiac is currently a full professor at Université Côte d’Azur, where he works on topics including Ginzburg-Landau models, harmonic maps, and variational methods. He has authored numerous research papers in leading journals, contributing to the mathematical understanding of vortices, phase transitions, and complex variational phenomena.

The paper for which Dr. Rodiac is receiving this award makes an important contribution to the study of the Ginzburg-Landau model for superconductivity by examining the difficult setting in which the number of vortices becomes unbounded and the limiting vorticities may concentrate along curves. The central question is how stability behaves in the mean-field limit and what this reveals about the structure of solutions. Dr. Rodiac shows that, for families of solutions whose rescaled energies converge to the expected limit, the second inner variation also converges to a natural limiting functional. The explicit computation of this variation is a key result in its own right.

What sets this paper apart is its clear and careful treatment of stability in a singular setting. It provides new insight into the behavior and regularity of limiting configurations and gives a partial answer to an open question from the Sandier-Serfaty monograph. Overall, the paper advances understanding of Ginzburg-Landau theory and points to promising directions for future work.

In short, Dr. Rodiac is receiving this prize for his rigorous and insightful contributions to the understanding of stability and limiting behavior in Ginzburg-Landau models, advancing both theory and open questions in the field. The CMS is pleased to award Dr. Rémy Rodiac the 2026 G. de B. Robinson Award.

About the G. de B. Robinson Award
The G. de B. Robinson Award is named for Gilbert de Beauregard Robinson, the third president of the CMS. Robinson, along with H.S.M. Coxeter, established the Canadian Journal of Mathematics (CJM) and acted as the managing editor for 30 years. The award recognizes outstanding contributions to the CJM, the Canadian Mathematical Bulletin (CMB), or the Canadian Mathematical Communications (CMC).

About the Canadian Mathematical Society (CMS)
The Canadian Mathematical Society (CMS) is the main national organization whose goal is to promote and advance the discovery, learning and application of mathematics. The Society’s activities cover the whole spectrum of mathematics including meetings, research publications, and the promotion of excellence in mathematics competitions that recognize outstanding student achievements. The CMS is a registered non-profit, charitable organization and depends on grants, funding, and generous donations from sponsors, benefactors and community members to be able to carry out its activities.
