We here describe the possibility of a synthetic description of the onset of Chaos in many degrees of freedom dynamical systems within the framework of the geometric description of dynamics. We show how this approach to instability helps to single out

In this paper we discuss some general aspects of the so-called "geometrodynamical approach" (GDA) to Chaos and present some results obtained within this framework. In order to support the claim that the GDA isn't simply a mere re-transcription of the

An effective Microcanonical Thermodynamics of self gravitating systems(SGS) is proposed, analyzing the well known obstacles thought to prevent the formulation of a rigorous Statistical Mechanics (SM), as those due to the formal unboundedness of avail

We analyse in detail the origin of some controversial points concerning the relationships between thechaotic behaviour of dynamics and therelaxation properties of Hamiltonian systems with many degrees of freedom (m.d.f.), showing that most claims exi

Using the tools of Differential Geometry, we define a new > chaoticity indicator, able to detect dynamical instability of trajectories much more effectively, (i.e. "quickly") than the usual tools, like Lyapunov Characteristic Numbers (LCN's) or Poinc

The thermodynamic behaviour of self-gravitating $N$-body systems has been worked out by borrowing a standard method from Molecular Dynamics: the time averages of suitable quantities are numerically computed along the dynamical trajectories to yield t

We use a geometrical description of the dynamics of Hamiltonian systems to single out the sources of instability (and of Chaos, if any). We show that: A) the instability is driven by the fluctuations of some geometrical invariants, rather than by the
