Resumen:
We present a
theoretical analysis of the global dynamics in a triaxial galactic system using
a 3D integrable Hamiltonian as a simple representation. We include a thorough
discussion on the effect of adding a generic non-integrable perturbation to the
global dynamics of the system. We adopt the triaxial Stäckel Hamiltonian as the
integrable model and compute its resonance structure in order to understand its
global dynamics when a perturbation is introduced. We provide a theoretical
discussion about diffusive processes taking place in phase space.
