Résumé : Summary: Formal theory of PDEs involves analysis of overdetermined systems, necessary before investigating the local/global aspects of integrability. It is based on differential and homological algebra, but also involves geometry. I report recent advances related to multi-brackets of a (non-linear) partial differential operators and discuss applications to solvability issues in geometry and physics.
