The unit of dynamic Systems devloped its activities following several research directions:
- celestial mechanics, planetology, space geodesy, within the framework of the dynamics of the Solar system or the exoplanets; the long-term behavior and stability, the orbital resonances or the spin-orbit are particularly studied.
- in the framework of Hamiltonian dynamics, the analysis of the chaotic dynamics is performed via techniques of the theory of the disturbances, adiabatic invariant, frequency analysis and averaging.
- numerical methods for the symplectic integration and chaos indicators computation.
- dynamics of generic dynamical systems with special attention to periodic orbits, limit cycles, normal forms and small divisors problems.
- application of dynamical systems tools to several fields, in particular to biology (models of protocells : stability and evolution), socio-dynamics (models of opinions dynamics and formation of groups of assent), economy (models of markets evolution), to medicine (determination and study of the new techniques for the determination of some neurodegeneratives diseases: Parkinson, ALS, Huntington).
- cosmology, including unified descriptions of dark matter and dark energy, N-body simulations of structure formation and derivation of observational constraints.
- general relativity and its extensions, notably tensor-scalar theories, numerical solutions to Einstein equations, and some approaches to quantum gravity.
- modeling of systems in terms of partial differential equations (e.g.reaction-diffusion equations).
