Walter Briec

Walter Briec is a Professor at the University of Perpignan, affiliated with the INSTITUT IAE and the LAMPS (Multidisciplinary Modeling and Simulation Laboratory). His research spans Mathematical Economics, Optimization, Operations Research, and Tropical Mathematics, with applications in productivity measurement, equilibrium concepts, and portfolio efficiency assessment.

• Section CNU 05, Economic Sciences
• Thematic axes: Nonlinear Analysis and Optimization, Physics of Complex Systems, Mathematical and Numerical Modeling for Mechanics

His research focuses on distance functions and their applications, including productivity indicators, game theory (cooperative and non-cooperative), and tropical mathematics. He explores duality-based methods, non-convexity in economic models, and convexity structures in financial portfolio selection. Projects like LAWBOT (Deep Learning for juridical outcomes) and BPS Customer Eco-Responsibility Analysis highlight his interdisciplinary work.

Article trends include non-associative algebraic structures, productivity growth analysis, game-theoretic approaches, and tropical mathematics. Collaborative works with researchers like Arnaud Abad, Kristiaan Kerstens, and Stéphane Mussard emphasize methodological innovations and real-world applications in economics and finance.
