The research group in Mechanics is focusing on the following topics: 1. Hamiltonian systems (integrability and non-integrability, stability, resonances, chaotic behavior) 2. Applications in celestial mechanics (main asteroid belt, Kuiper zone, extrasolar planetary systems) 3. Applications in grid dynamics (oscillations and stability) 4. Inverse problem in dynamics and relation of families of orbits το integrability 5. Application of the theory of dynamical systems to the dynamics of biological populations.
