Yvon Maday Chaire Les chaires Collège de France Année 2025-2026 Colloque : Aspects mathématiques et appliqués des méthodes de réduction de complexité Yvon Maday, chaire Informatique et sciences numériques Colloque - Jörg Fehr : Yvon Maday, chaire Informatique et sciences numériques Jörg Fehr Résumé The simulation and optimization of complex technical systems often require models that are both sufficiently accurate and computationally efficient. In engineering practice, this balance is difficult to achieve: detailed numerical models provide valuable insight, but they are frequently too costly for repeated evaluations, design optimization, uncertainty studies, or real-time applications.
