Resumen:
In the present lectures we provide results and discussions concerning the processes that lead to local and global chaotic diffusion in phase space of multidimensional conservative systems. We investi- gate and provide a measure of the extent of the domain over which diffusion may occur. All these issues are thoroughly discussed by deal- ing with a toy model such as the perturbed quartic oscillator as well as with a multidimensional conservative map that would be representa- tive of the dynamics of a resonance interaction, which is an important mechanism in several astronomical systems, like the Solar System or galaxies.
