A symplectic approach to gravitational instability
J. Perez, M. Lachieze-Rey
We present a global approach of non-dissipative physics. Based on symplectic mechanics this technique allows us to obtain the solution of a very large class of problems in terms of…

Stability of spherical stellar systems I : Analytical results
J. Perez, J-J Aly
The so-called ``symplectic method'' is used for studying the linear stability of a self-gravitating collisionless stellar system, in which the particles are also submitted to an ex…

Stability of spherical stellar systems II : Numerical results
J. Perez, J-M Alimi, J-J Aly +1
We have performed a series of high resolution N-body experiments on a Connection Machine CM-5 in order to study the stability of collisionless self-gravitating spherical systems. W…
